esskar has asked for the wisdom of the Perl Monks concerning the following question:

my module needs for exactly one function the module Math::XOR. So i thought includding it by "require Math::XOR" in the scope of the function since the function is not used very much.
but if i use "require", perl says that it can't find xor_buf. I ve tried Math::XOR::xor_buf also with no success.
Any hints?
