That's logically poor: being an lvalue sub is a more intrinsic property
of the sub than its name is. But it's also ruled out by "sub :" parsing
as a label. For anonymous subs the label syntax causes a problem, but
the ambiguity is resolvable by preceding "sub :lvalue" with a "+". For a
named sub declaration, which is syntactically a statement rather than an
expression, no such disambiguator would be available. Even if there were
a disambiguator, it would be a poor decision to introduce new ambiguity,
and especially poor for some bit of syntax to need disambiguation every
time it's used.
