Re: while () vs. while (1)

And it is strange that the statement modifier has a different effect:

print "Here\n" while();
[download]

does not produce an infiinite loop, whereas:

while(){print "Here 2\n"}
[download]

does, which is a bit inconsistent.

Update: I just tried the following in Rakudo*:

# perl6

while () {
    say "Hello"
}
[download]

and it did not give an infinite loop, it dropped straight through. That might be an effect of () being an empty list (false), so I tried

while {say "Hello 2"}
[download]

but that would not compile. The bare loop statement is specifically for infinite loops in p6 SFAIK, but

while 1 {say "Hello 2"}
[download]

also works as expected.

You seem to have forgotten that statement modifiers don't use parens. `# EXRP while EXPR; print "Here\n" while ();` [download] is the equivalent of `# while (EXPR) { EXPR; } while ( () ) { print "Here\n" }` [download] Both behave identically.	[reply] [d/l] [select]
