[squeak-dev] Protocol extension proposal: Boolean>>asBit ?

I currently writing a code which looks like:
a := some numeric expression + (someBoolean ifTrue:  ifFalse: ).
And i get somewhat tired repeating the same pattern in multiple places.
So, i thinking , maybe #asBit convenience method could be useful?
so, then, in case of need like above, we could write much shorter expressions:
a := some numeric expression + someBoolean asBit.
And its much less error prone comparing to #ifTrue:ifFalse:, since i
found its relatively easy to make a mess (swapping 1 with 0),
especially, when you having negations in expression, because once you see:
(someBoolean not ifTrue:  ifFalse: )
you always tempted to write it as:
(someBoolean ifTrue:  ifFalse: ).
(someBoolean ifFalse:  ifTrue: ).
but once you start playing with it, its very easy to shoot into own
feet if you are not careful.
But if we could add #asBit, then we could write:
someBoolean not asBit
which is much more:
a) concise & cleaner
b) error proof
