You can also use:bool b = someComplicatedStuff();b = b || otherComplicatedStuff(); // it has to be: b = b || ...; b |= ...; is bitwise OR and SCE is not working then and SCE will work.But it's not much...

1) Yes, you no longer have SCE. Otherwise, you would have that bool b1 = SomeComplicatedFunctionCall();bool b2 = OtherComplicatedFunctionCall();works one way or the other depending if there is an if...
