The subname() function exported by this module allows one to assign new names to Perl subroutine. This is different from glob-assignment, since the name is only used for informational purposes (caller, Carp, etc.). Note that for anonymous closures (subs that reference lexicals declared outside the sub itself) one can name each instance of the closure differently, which can be very useful for debugging.
