Same for me.

I could survive it because it is linked to the "do:" header. But the real drawback for me is that it should rather express the exit-condition, because it is placed at the end.
Anyway, I would support the "while" version if "until" gets to much opposition (for introducing 2 new keywords instead of only 'do').
Both are much better imo than the header versions.
