5 To install this module type the following:
16 Sub::Name - (re)name a sub
21 subname $name, $subref;
23 $subref = subname foo => sub { ... };
26 This module has two functions to assign a new name to a sub -- in
27 particular an anonymous sub -- which is displayed in tracebacks and
28 such. Both functions are exported by default.
31 Assigns a new name to referenced sub. If package specification is
32 omitted in the name, then the current package is used. The return value
35 The name is only used for informative routines (caller, Carp, etc). You
36 won't be able to actually invoke the sub by the given name. To allow
37 that, you need to do glob-assignment yourself.
39 Note that for closures (anonymous subs that reference lexicals outside
40 the sub itself) you can name each instance of the closure differently,
41 which can be very useful for debugging.
