As a guess, maybe Noah wanted it to mean the same as it does in C++?
Ie., that it's only initialised the first time it's seen (not applicable
to DGD LPC as it doesn't have initialisors) and if the function is called
again, the variable retains the value it had at the time the last call to
the function finished.  In a nutshell a static variable inside a function
in C++ is just a way to create a global variable which has the scope of
being inside a function (so other functions in the same global namespace
can't access it).
