+1 . IfThen instricit is IMO very bad idea. I have a lot of "IfThen" from
math and strutils modules.

IfThen from System totally breaks the compatibility :\ . C'mon Sven. In one
field you're rigorously but in something like this you're liberal
(braking/dangerous change / for existing code base).

If i understand correctly "ThenExpr" is executed only when "Condition" is
true and "ElseExpr" is executed only when "Condition" is false. For
standard "IfThen" from Math and StrUtils "ThenExpr" and "ElseExpr" is
executed before IfThen is called.

for me different syntax for System.IfThen is required (fpIfThen ? or
http://docs.elementscompiler.com/Oxygene/Expressions/If/ ).
