To quote:

They're definitely two different kinds of loops. However the text for and foreach may be used to introduce either one. The actual loop-style is determined by what follows.
Which, seems to me, answers the question:
What is the difference between for & foreach, exec & system
as "for & foreach are aliases - there is no difference. They both introduce either a for-style loop or a foreach-style loop, determined by what follows."

Methinks you're getting a bit bent out of shape over someone agreeing with you. Either that, or I'm completely missing your point.

    It's a language (English) problem - for and foreach are words but they also designate the style of the loop, which I think is what merlyn is getting at.

    The words are aliases, the loops are not, as they are taken in context. It sounded like the disagreement was over:
    for & foreach are now an alias to each other
    which is ambiguous

    "But what of all those sweet words you spoke in private?"
    "Oh that's just what we call pillow talk, baby, that's all."
