3 To install this module type the following:
14 Sub::Name - (re)name a sub
19 subname $name, $subref;
21 $subref = subname foo => sub { ... };
24 This module has only one function, which is also exported by default:
27 Assigns a new name to referenced sub. If package specification is
28 omitted in the name, then the current package is used. The return value
31 The name is only used for informative routines (caller, Carp, etc). You
32 won't be able to actually invoke the sub by the given name. To allow
33 that, you need to do glob-assignment yourself.
35 Note that for anonymous closures (subs that reference lexicals declared
36 outside the sub itself) you can name each instance of the closure
37 differently, which can be very useful for debugging.
