Absolutely agree. Personally I find: the Perl way of doing things is either while() or for (@list). This is for a variety of reasons.

First of all, if you have a loop, it should be obvious that it is a loop. (To take it to extremes, that's what BASIC's GOSUB did wrong - it is a subroutine call, but the called place doesn't look like a subroutine.)

Also, the for(;;) form is to be avoided; most of the time you can write it as for (@list). Perl understands the notion of a list natively so you should not concern yourself with index variables. This eliminates an entire class of coding errors - the fencepost errors which consist in mostly overlooking nasty special conditions that result in the loop executing once more or less than it should. for(;;) also is inefficient (internally, it is handled like a while () {} continue {} construct).

{ ... ; redo } has its place just like for(;;) is occasionally useful - but for the sake of your own sanity you should not make either of them a habit.
