is it "pgfluamath.functions.lua" a safe name for a Lua module ?
 
http://www.lua.org/manual/5.2/manual.html#pdf-package.searchers

"""
The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.
