Re^5: Interview Prepration

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
