Conditional lua_yield

[Enrico Colombini <erix@...>]

The manual states that lua_yield "should only be called as the return 
expression of a C function".

Can I have a conditional yield on return? e.g. is this valid or could it 
give trouble (possibly depending on the compiler)?

 if (mustYield) {
     return lua_yield(lua, 0);
 } else {
     return 0;
 }

I suppose so, but just to be safe...
