There's no official API for this, but you can look inside ldo.c and luac.c
and see how it's done: "lua_parsestring" would be luaY_parser;
"lua_doblock" would be luaD_protectedrun.

Well, the whole point of loading a chunk is to have some side-effects!
(At least, some function definitions, which are simply assignments.)
Now, as you say, "chunks" are probably different from what you call "modules".
But I think Lua has the mechanisms to allow you to define your own semantics
for "modules", e.g., the setglobal tag method.
