libsafe-isa-perl - 1.000010-1 main

Since Perl allows providing a subroutine reference, or a method name, to
the -> operator (when used as a method call) and a subroutine doesn't require
the invocant to actually be an object, Safe::Isa can be used to create safe
versions of isa, can, does and DOES by using a subroutine reference that
only tries to call the method if it's actually used on an object.
