Don't hesitate to put some "Guru" tips in comments. Because it's really hard to know its own misconceptions :) I don't think it would break the fun (well.... unless you write "stupid idiot bastard don't use String>>#asUrl burn in hell !!!") but bring emulation. Laurent

Indeed I don't like '2010/08/01' asTime, but I like 3 seconds.
And I think the reason is the following:
'2010/08/01' asTime
this is just code... "string, you smalltalk object, please convert
yourself into an object of another class that
you normally should know too much about". No reason why not to ask the Time class: hey, time, I have a string, can you make a time for me? And it's even nicer... Time knows about time, string about being a string.
Yes. So I think I should avoid to show 'http://www.google.com' asUrl in pharocasts......

BUT:
1 second + 3 hours
This is different. This is a *domain specific language* for dealing with time. When you read that, you do not think in term of general smalltalk code for coverting between classes. We are (kind of) outside of our language model and the rules we normally follow do not apply. (e.g. there is no hour and second class...).
Domain specific languages are powerful, and one can abuse them very easily. (am guilty of having written once some awful DSL where even the *name* of a block parameter had semantic meaning ;-)
