[squeak-dev] Avoiding compiler inlining

Following cascading of macros, I need turning some inline off. A
recurrent topic in Squeak-dev.
Well, once i thought about using a Compiler reflective annotation (i.e.
a pragma) in order to turn optimization off.
Stupid me.
Inlined messages are made of block receiver/arguments.
So one would simply turn inlining off by sending a yourself message to a
block.
[false] yourself whileTrue.
false ifTrue: [self inspect] yourself.
Of course, yourself is not a very explicit message...
We could create another #turnOffInlining or something...
Except that in Squeak as other Smalltalks, the Old Compiler is quite
pedantic about optimizing these messages.
[false] yourself <- receiver of whileTrue must be a block or variable
->whileTrue.
false ifTrue: [self inspect] <- argument of ifTrue: must be a block or
variable ->yourself.
Common! You don't like the system? Change It!
This is just 1 method attached.
Ah, and the ifNil test is just a trick for the cascades, remember?
Isn't life easier with Smalltalk compared to a static world?
