in reply to Re: GOTO considered (a necessary) evil?
in thread GOTO considered (a necessary) evil?

But a redo (just like next and last is just a glorified goto.

I consider this statement blatently false and missleading.

This typo generates an error...

perl -le 'BAR: print 1; BAZ: for (2..3) {print; redo BAR; }'

This typo causes an infinite loop...

perl -le 'BAR: print 1; BAZ: for (2..3) {print; goto BAR; }'

(Updated to be less pedantic... the point is, goto is for arbitrary jumping, redo is for controlled jumping to the begining of a loop. Could you live w/o redo if you had goto? yes. Does that mean you should just use goto and not bother with redo? no.)
