Hey guys,

I was discussing about methods like that with Marcus:

MyClass>>foo

#(false) first��

ifFalse: [��

'first call since compilation' logCr.��

#(false) at: 1 put: true ]

ifTrue: [ 'other calls' logCr ]

DoIt:

4 timesRepeat: [MyClass new foo ]

Transcript:

'first call since compilation'

'other calls'

'other calls'

'other calls'

In the sista image/VM, we are most probably going with Eliot to implement a slow path when you edit the literal of a method (deoptimizing the method) so we can consider that the literals are immutable in the generic case (and if it's not true, execution falls back to a slow path).

But I was thinking, does it worth it to implement the slow path ?��

Couldn't we just put literals as immutable all the time ?��

The methods as the one shown before would not work any more. But does someone use it ?
