Short Question:

Is type globbing of subroutines possible or not?

for something like

&supersub(\&smallsub);

yes,

perl -le 'use warnings; use strict; \
sub sub1{1}; \
*sub2=\&sub1; \
warn sub2(); \
'

This (passing a subroutine reference as argument to a subroutine):
is unrelated to the above.

perl -le 'use warnings; use strict; \
sub sub1{shift->()}; \
sub sub2 {2}; \
warn sub1(\&sub2);
'

It is possible but using references is the preferred method.
