You need to write an extension. The included parallelmagic extension shows one
way, using a Plugin:
This is useful when you need to keep track of state as attributes on the Plugin
My kernmagic package shows another way to expose individual magic functions that
do not have state:
"I have come to believe that the whole world is an enigma, a harmless enigma
that is made terrible by our own mad attempt to interpret it as though it had
an underlying truth."
