Re: How do I write subs that take bare blocks as args?

Couldn't this be done with a grep?

if (grep {$_->price <= 1000} @product_list) {
    # do stuff
}

Hey, good idea! Except, to work the same as my example, it needs to be: `if ( ( grep { $_->price <= 1000 } @product_list ) == @product_list ) { # do stuff }` [download] _______________ D a m n D i r t y A p e Home Node \| Email	[reply] [d/l]

Why so complicated? :) `if(not grep { $_->price > 1000 } @product_list) { # do stuff }` [download] Update: `my @p = (0,2,4,5,2,5,7,7); print "1: none\n" if not grep { $_ > 1000 } @p; push @p, 1002; print "2: none\n" if not grep { $_ > 1000 } @p; =output 1: none` [download] `____________` Makeshifts last the longest.

You are right. In my example the `{ #do stuff }` block will get executed if any of the members of `@product_list` pass the conditions. You want to know if all members pass. IIRC won't perl6 have some kind of `any` and `all` builtins? -- flounder	[reply] [d/l] [select]

It will. But Quantum::Superpositions will give them to you now. (Warning: This module is superfreaky.) We are using here a powerful strategy of synthesis: wishful thinking. -- The Wizard Book	[reply]
