Perl module enabling one to delete subroutines
This module provides one function, delete_sub, that deletes the subroutine whose name is passed to it. To load the module without importing the function, write use SubDelete;.
This does more than simply undefine the subroutine in the manner of undef &foo, which leaves a stub that can trigger AUTOLOAD and, consequently, won’t work for deleting methods. The subroutine is completely obliterated from the symbol table though there may be references to it elsewhere, including in compiled code.
