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.
