11 subname $name, $subref;

13 $subref = subname foo => sub { ... };

16 This module has only one function, which is also exported by default:
17
18 subname NAME, CODEREF
19
20 Assigns a new name to referenced sub. If package specification is
21 omitted in the name, then the current package is used. The return
22 value is the sub.
23
24 The name is only used for informative routines (caller, Carp, etc).
25 You won't be able to actually invoke the sub by the given name. To
26 allow that, you need to do glob-assignment yourself.
27
28 Note that for anonymous closures (subs that reference lexicals declared
29 outside the sub itself) you can name each instance of the closure dif‐
30 ferently, which can be very useful for debugging.
