More accurately, it should return the number of values it pushed,

That would simplify returning a value slightly:
return lua_pushinteger(L, 42);
instead of:
lua_pushinteger(L, 42);
return 1;
How about
return (lua_pusxx(), 1)
A clever hack, but there's a high likelihood of confusion since the language being interfaced with supports multiple return values, whereas comma operator hacks in C are considered bad form. /s/ Adam
With the odd special exception (for example, it’s nearly impossible to write a decent assert() macro without it).
