1 | package Sub::Name; |
2 | |
3 | =head1 NAME |
4 | |
5 | Sub::Name - (re)name a sub |
6 | |
7 | =head1 SYNOPSIS |
8 | |
9 | use Sub::Name; |
10 | |
11 | subname $name, $subref; |
12 | |
13 | $subref = subname foo => sub { ... }; |
14 | |
15 | =head1 DESCRIPTION |
16 | |
d73d8321 |
17 | This module has only one function, which is also exported by default: |
16c23894 |
18 | |
19 | =head2 subname NAME, CODEREF |
20 | |
21 | Assigns a new name to referenced sub. If package specification is omitted in |
22 | the name, then the current package is used. The return value is the sub. |
23 | |
24 | The name is only used for informative routines (caller, Carp, etc). You won't |
25 | be able to actually invoke the sub by the given name. To allow that, you need |
26 | to do glob-assignment yourself. |
27 | |

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