Because all this discussion is being on the possibility of having an operation on a _non_ Complex number return a Complex result, so the test is kosher and you can go. _If_ you return an argument that something already was a complex number then all this argument is moot... Let me restate where we started from. We started from point: Array new: 0.2i which simply shown that there are many places where complex numbers appearance (or even non-integer numbers) is undesirable. But since you insisting on introducing the functions which do implicit conversions under the hood, without real intent of developer, how he could be sure that above not happens? And then same, in next example: (something positive) ifTrue:[something sqrt ] IfFalse: [ 5 ] how you can be sure that 'something' is not complex number already, and therefore, sending #positive to it is meaningless? > > [snipped] > >> > Once you put Complex in the Smalltalk paradigm, I think we should preserve >> > as much as possible this design decision made at the start of the language. >> > From a programming POV -4 sqrt mapping from Real to Imaginary (Complex) is >> > homologous to 13 / 3 giving a Fraction.

Where i see the difference is, that for real numbers you need to represent a single value (and no matter by what you representing it - because it is still Real value), while for complex number you need a two distinct values (but they could be represented by any real values you desire). But since you don't see such difference and advocating that complex is just a 'more generic' representation of real, an no-one should care where it seamlessly appears and when (because of implicit coercions), then give me the answer, where you want to stop: 1. Two different ways representing real value: 1/2 <=> 0.5 2. Two different ways representing ?same? value: 0.5 <=> 0.5 + 0i 3. Three different ways representing ?same? value: 0.5 <=> 0.5 + 0i <=> Complex real: (0.5 + 0i) imaginary: (0 + 0i) 4. Four different ways representing ?same? value: 0.5 <=> 0.5 + 0i <=> Complex real: (0.5 + 0i) imaginary: (0 + 0i) <=> Complex real: (0.5 + (Complex real: 0+ 0i imaginary: 0 + 0i)) imaginary: (0 + 0i) and so on... >> >> I simply wanted to illustrate you that passing values to code which >> not expecting the Complex values >> having same side effect as passing a Complex values to members of >> Complex value (real/imaginary) part, and state that its ok. > > I'm sorry to inform you that until now you have not achieved your intent in showing me a robust case. . . > >> >> That's why its is good to have separation from functions which >> operating with reals only and can NEVER return anything else than real >> values from functions which can return complex values. > > I maintain my opinion that this is not helpful to make Pharo (having an implementation like this) compelling for doing work with this kind of programming.

Make sure that both versions A and B are stored as Monticello Packages (probably to a local directory). 2. Load version A. 3. Load version B. 4. In the changes-browser there is now a new change-set named A->B. 5. Open a change browser on it and edit it as you like. 6. File-out the change-set. What I usually do is different and I think goes better with the whole workflow of Monticello: 1. In an image where I have the modified code I display the changes between the previous version (A) and the current image (B). 2. Then I selectively revert the changes that I don't want to go into B. 3. And commit the package B. >> b) Supose the change includes 3 separate packages, that should be >> seen as a one. Loading only one package only would break things, so >> I'd like the change to include all 3 in one operation. It is possible to create custom PackageInfo subclasses (Seaside <= 2.8 did this), but I have rarely seen this and don't find it particularly useful. I would stick to the original packages to make merging for the maintainers easy. Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Re: [Pharo-project] Analog to Dolphin's #forkMainIfMain?

Bill (and igor) I would love to continue to remove Project from the image so the "spawnProcessIfThisIsUI:self activeProcess." should probably find another host.
