It could also behave as our bool type. Something that you can attach
properties to but doesn't need a value seems that it could be useful
every once in a while.
Just... what does a void literal look like? Perhaps just the word
C<void>?
my void $false_var = void but false;
I'm just speculating. But I do see a use for it.
