Are parentheses around the result significant in a return statement?

Question

Is there a difference between these two statements inside a function?

bool returnValue = true;
// Code that does something
return(returnValue);

Answer 1

You're abusively slowing down the compiler!

The presence of parenthesis not only slow down the preprocessing phase, but they generate a more complicated Abstract Syntax Tree too: more memory, more computation.

From a semantic point of view ? They are exactly identical. Whether there are parenthesis or not the return statement will fully evaluate the expression before returning it.
