Switch to ~null~ and ~void~ (vs
<opt>
and <void>
)
A long time ago when there was only one state you could put in values that could not be in blocks, it was called VOID. It didn't have a datatype, so some alternative signal was needed in the type spec blocks. The idea of using a TAG! and saying `<opt>` was chosen as a temporary solution. That temporary solution wound up lasting for many years, as the lack of a satisfactory answer persisted. The type changed from being VOID to being NULL, and then something called VOID came along with a similar problem. So `<void>` was used for that. As the needs to be more expressive about the properties of parameters grew, tags began to control other features...making it a bit saturated to also be using tags for void and null indications. The modern idea is to use quasiforms to represent their antiforms, and it seemed like a pretty reasonable solution...but didn't fit the situation with void not being an antiform of the word "void" But that's changed, and now void *is* the antiform of the word void. So ~void~ makes a good indicator in the typespec if you want to call more attention to it than with the function VOID?. So this finally bites the bullet and shifts to using ~null~ and ~void~.
