( #3333=superdoc: print w/replies, xml ) Need Help??
hmm maybe simpler than we thought!

DB<25> sub first (&@) { my $code=shift; grep {return $_ if &$code} @ +_ } DB<26> first { $_ >5 } 1..10 => 6 DB<27> first { $_ >10 } 1..10 DB<28> sub any (&@) { my $code=shift; grep {return 1 if &$code} @_ ; + ()} DB<29> any { $_ >10 } 1..10 => "" DB<30> any { $_ >5 } 1..10 => 1

Can you spot problems?

update

variation of first for finding position

DB<40> sub position (&@) { my $code=shift; my $idx=-1; grep {++$idx; + return $idx if &$code} @_ ; ()} DB<41> position { !$_ } 1..10,undef,11..20 => 10

update

changed "" to () for false.

update

even easier

DB<53> sub first (&@) { my $code=shift; &$code and return $_ for @_ +; ()} DB<54> sub any (&@) { my $code=shift; &$code and return 1 for @_ ; ( +)}
