Greetings gentle monks,

is there a magic way to call an anonymous subroutine within its own body without binding it to a coderef ?

I'd like to do something like that:
(sub {... magic(...) ... )->(args)
where magic would refer to the anonymous sub being defined.

The closest I came so far was
use strict; { my $coderef; ($coderef = sub { ... $coderef->(...) ...)->(args); }
which strikes me as inelegant and potentially leaky. Here is some runnable (if silly) code :
use strict; # direct call of unbound non recursive anonymous subroutine my $res = (sub{ print @_[0] + @_[1] . "\n\n";})->(100,1); # need to bind to a coderef if recursive ? { my $coderef; ($coderef = sub {return unless $_[0] > 0; print "$_[0]\n"; $codere +f->($_[0]-1)})->(4); }

In real life, I sometimes need to call a recursive function or subroutine to process a tree-like structure. It gets called only once, at a specific point, and should (IMO) not need to be graced with a name or bound to a coderef (much in the spirit of a map {...} @somearray).

Any thoughts ? TIA.

      Should cpanminus be part of the standard Perl release?
