return with or without parentheses

[harryma23]

According to https://www.mql5.com/en/docs/basis/operators/return, 

we should enclose the value or expression to be returned in parentheses, for example:

int CalcSum(int x, int y)
  {
   return(x+y);
  }

But the following does also work:

int CalcSum(int x, int y)
  {
   return x+y;
  }

Is there a subtle difference between return statements with and without parentheses?

It's the same.

Though personally I find more readable to use ().
