ah, yes. yes, it does.
is this somehow dependent on the number of the current tab such that
it couldn't be part of the menu (popped up by 3d button mouse click
on "FvwmTabs")?

unless you are using non-parenthesis version of subs, it really does
not matter where you declare/define subs. if you do keep '&', then
you are wasting your efforts by defining prototypes as prototype
checking will be ignored.
perlsub(1) SYNOPSIS says it quite succinctly & clearly...
To call subroutines:
NAME(LIST); # & is optional with parentheses.
NAME LIST; # Parentheses optional if predeclared/imported.
&NAME(LIST); # Circumvent prototypes.
&NAME; # Makes current _at__ visible to called subroutine.
