"normal subs" are just named "anonymous subs", there is not much more difference.
consider
DB<7> *beyonce = sub { print "say my name, say my name" }
DB<8> beyonce()
say my name, say my name
DB<9>
this also works the other way round, you can read the sub-ref of a named sub and than destroy the name in the packages STASH:
DB<21> sub kelly { print "say my name, say my name" }
DB<22> $anosub = \&kelly
DB<23> delete $main::{kelly}
DB<24> $anosub->()
say my name, say my name
DB<25> kelly()
Undefined subroutine &main::kelly called at (eval 34)[c:/Strawberry/pe
+rl/lib/perl5db.pl:738] line 2.
So where do you want to draw the line???
side-note
there are though block-compounds in Perl which can be confused with anonymous subs.
Maybe that's your misunderstanding, if you talk about "inlined subs" °?
for instance map-blocks are not ano-subs effecting return
DB<19> sub tst { map { return $_ } 42..1e6 ; return "never executed"
+ }
DB<20> p tst()
42
DB<21>
But those map-like constructs in List::Util are implemented with ano-subs and won't allow returning from outer subs!
°) what does that even mean? |
