25DESCRIPTION
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.
29
30 subname NAME, CODEREF
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
33 is the sub.
34
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.
38
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.
