I have already referred to Ada and I will again. Ada as I see it have
the perfect solution: The loop variable is declared in the FOR-
statement, and is thus not accessible afterwards. I can't but see 
that that definition solves the problems. No, if this had possible
for WHILE-loops to!

A side note: Since REPEAT loops are quite rare and an source of
error when used in the wrong place, it surprises me that Wirth
removed too, to make his compiler even simpler.
