Re^2: Useful uses of redo?

I guess you can do:

{                       # do {
   stmt;
   stmt;
   stmt;
   redo if $cond;       # } while ($cond);
}

and

{                       # repeat {
   stmt;
   stmt;
   stmt;
   redo unless $cond;   # } until ($cond);
}
[download]

but why? yuck! It's like saying that while loops while henceforth be like:

{
   last unless $cond;    # while ($cond)
   stmt;
   stmt;
   stmt;
   redo;                 # wend
}

`do { }` still exists. It's just the statement-modifier while-on-do that is taken away.	[reply] [d/l]

So are you saying that in perl6 the following won't be valid: do { $foo = foo(); $bar = bar(); } while ($foo != $bar); ?? That would suck!	[reply]
