131 .IX Title "Sub::Name 3"
132 .TH Sub::Name 3 "2008-07-18" "perl v5.8.7" "User Contributed Perl Documentation"
134 Sub::Name \- (re)name a sub
136 .IX Header "SYNOPSIS"
142 \& subname $name, $subref;
146 \& $subref = subname foo => sub { ... };
149 .IX Header "DESCRIPTION"
150 This module has only one function, which is also exported by default:
151 .Sh "subname \s-1NAME\s0, \s-1CODEREF\s0"
152 .IX Subsection "subname NAME, CODEREF"
153 Assigns a new name to referenced sub. If package specification is omitted in
154 the name, then the current package is used. The return value is the sub.
156 The name is only used for informative routines (caller, Carp, etc). You won't
157 be able to actually invoke the sub by the given name. To allow that, you need
158 to do glob-assignment yourself.
160 Note that for anonymous closures (subs that reference lexicals declared outside
161 the sub itself) you can name each instance of the closure differently, which
162 can be very useful for debugging.
