IfThen is not ok. It can potentially break compatibility. The probability
is huge. IfThen is in many cases the only function that is used from Math
or StrUtils. I have big codebase to maintain which is refactored very
often. The risk to omit Math and StrUtils is very big.

It can be very hard to debug.

There are so many ways to implement this and was chosen the worst scenario.
