Sub::Name(3)                         User Contributed Perl Documentation                        Sub::Name(3)



NAME
       Sub::Name - (re)name a sub

SYNOPSIS
           use Sub::Name;

           subname $name, $subref;

           $subref = subname foo => sub { ... };

DESCRIPTION
       This module has only one function, which is also exported by default:

   subname NAME, CODEREF
       Assigns a new name to referenced sub.  If package specification is omitted in the name, then the
       current package is used.  The return value is the sub.

       The name is only used for informative routines (caller, Carp, etc).  You won't be able to actually
       invoke the sub by the given name.  To allow that, you need to do glob-assignment yourself.

       Note that for anonymous closures (subs that reference lexicals declared outside the sub itself) you
       can name each instance of the closure differently, which can be very useful for debugging.
