Right. They're syntax aliases, but they're semantically entirely different things. Did you read what I quoted? It explains what I mean, and I don't want to keep retyping that. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

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.	[reply] [d/l] [select]

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."	[reply]


Problems? Is your data what you think it is?
