I think they added a IfThen generic which can be implicitly specialized now
so you can do things like:

  s := IfThen(p <> nil, 'valid', 'nil’);

vs

  s := If p <> nil then 'valid' else 'nil';

It’s almost easier to read. I’m not sure I’d like the have if-statements
confused with expressions when scanning code either. At least the C version
is more terse but that one can be hard to identify also. All in all I think
IfThen is actually pretty good.
