Well, pretend you have a real one... and it'll behave like a real one.

How pickier is it possible to get?

Tell your brain to parse "end while" as one token.

Does it have to be called "repeat" and "until" too?

It's not a matter of deciding what's the best overall type of loop and 
call all other ones ugly. Just pick the appropriate construct for the 
situation. The construct is the appropriate one if it doesn't make you 
jump through hoops.
