Labels

[pne]

It doesn't seem possible to create labels at the moment (i.e. "LABEL: code" or "LABEL: { BLOCK }").

This makes goto pretty much useless, and means that "redo next last" currently only work in their bare, label-less forms.

Trying to put "LABEL: code" results in a parse of { acc => "LABEL" } + { acc => ":" } + { cmd => "code" }, i.e. two arguments of $LABEL and $:, which is not really what we want...

If we decide to use a verb to declare labels, {per} might be appropriate ("(n) label; (v) label, ascertain, specify"). It doesn't appear to be in use yet, either.
