If you can show me a single instance in which the use of "for" instead of "foreach" makes a difference in code, I'll believe you.

    Do you mean the word for exchanged for the word foreach? No. Those keywords are syntactically equivalent. And I don't disagree with that fact.

    Do you mean replace a for loop with a foreach loop, or vice versa? Certainly! They have different semantics!

    The keyword "for" is the same as the keyword "foreach". The "for" loop is different from the "foreach" loop. Do I need to keep repeating this? {sigh}
