I beg to disagree.This is completely backwards -- like saying that
"while" loop is an
ugly hack to save some typing of "goto" operators.
Iterators and foreach loops are very important tools of structured coding.
The fact that "for..in" may be expressed in terms of lower-level primitives
does not decrease its importance, just like existence of "goto" does
not decrease
the importance of "while".
