what dwimmery you talking about?
b := [ 15 ].
a := [ 16 ].
true ifTrue: a ifFalse: b
16
as well as:
b := 15 .
a := 16 .
true ifTrue: a ifFalse: b
16
works well.
In this way,
answer := process ifNotNil: #terminate.
should be equivalent to:
answer := process notNil ifTrue: #terminate
but not to:
answer := process notNil ifTrue: [ process terminate ].
