Package: libsafe-isa-perl (1.000010-1)

module for safely calling isa and friends on things that may not be objects

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.
