package Sub::Name; # git description: v0.26-4-gf9cd47d
# ABSTRACT: (Re)name a sub
# KEYWORDS: subroutine function utility name rename symbol

#pod =head1 SYNOPSIS
#pod
#pod use Sub::Name;
#pod
#pod subname $name, $subref;
#pod
#pod $subref = subname foo => sub { ... };
#pod
#pod =head1 DESCRIPTION
#pod
#pod This module has only one function, which is also exported by default:
#pod
#pod =for stopwords subname
#pod
#pod =head2 subname NAME, CODEREF
#pod
#pod Assigns a new name to referenced sub. If package specification is omitted in
#pod the name, then the current package is used. The return value is the sub.
#pod
#pod The name is only used for informative routines (caller, Carp, etc). You won't
#pod be able to actually invoke the sub by the given name. To allow that, you need
#pod to do glob-assignment yourself.
#pod
#pod Note that for anonymous closures (subs that reference lexicals declared outside
#pod the sub itself) you can name each instance of the closure differently, which
#pod can be very useful for debugging.

=head1 DESCRIPTION
This module has only one function, which is also exported by default:
=for stopwords subname
=head2 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.
