Re: [Pharo-users] How does Boolean ifTrue work?

by Dimitris Chloupis

Igor you confuse me with someone else I never asked why Smalltalk doesn't have... nor I said that I want static types and interfaces. I am actually trying to use a Pharo instead of C++ with Unreal. I hate static types and I hate interfaces. Only pointed that is possible. I don't like languages that think they are smarter than me. I love my freedom thank you very much and I love Pharo as it is language wise.

' when you know that in smalltalk you can do anything you want? Yes, you can do anything you want, but not everything you can do makes sense to do. And it doesn't defeats the purpose of smalltalk, it just defeats the common sense. And last one, i don't understand what kind of 'exposure to internals' you are talking about. In smalltalk people used to write a functional tests, to check that your code behaves as intended. Now you proposing to introduce static interfaces, borrowed from other lanuages, the only purpose of which is to declare that your code *could* behave as intended, no guarantees , nothing. Just a set of formal rules on top of existing ones, with ZERO end effect and benefits. You want it? You are free to implement it. Good look with it.. I wonder, why so many people think that if they put soft pillows everywhere, seal the doors (because outside is dangerous) , and after sealing and pillowing everything they happily rest with thought 'now we are safe'.. not realizing, that they built a perfect jail for themselves, without any means to escape from it and do something in real world.
