`showtype` vs `$showtype`

Is there any differences between showtype and $showtype? (seems there
is no) Is one to be preferred over the other? I feel to guess $showtype
is to be preferred.

If both exist, is this because $showtype was added in case showtype is
overloaded?

Is it the same with all others $xyz?

See the end of the file:

showtype is a macro defined to be $showtype. There are also showview and
