Actually this code:
True basicNew ifTrue: [ "some code" ]
works fine on the latest Pharo 3 because of Opal :)
So the Opal compiler lacks important optimizations. :)
Not at all. In fact, the the code is optimized and falls back to the normal
lookup in case of exceptional #mustBeBoolean, so the existing code keeps
running the same speed ;)
So it generates a bunch of extra bytecodes for every #ifTrue:, #ifFalse:,
#ifTrue:ifFalse: and #ifFalse:ifTrue: messages, in order to make this
thing work? Or is there a trick to avoid the duplicaiton of the code in
the blocks?

But nice trick for the old compiler :)

Because you don't know the tricks... This one should be just
fine
True basicNew ifTrue: [ "some code" ] yourself
2013/6/26 Clément Bera <[email protected]>
True basicNew ifTrue: [ "some code" ]
hehe raises NonBooleanReceiver :)

why not, let's "forbid" them with an error message!
=> maybe you can and error to #become: on nil / true / false
as well?
