( #3333=superdoc: print w/replies, xml ) Need Help??
map and grep are very different beasts, cause the block is NOT handled like an anonymous sub but more like a do-block.

DB<117> sub tst { map {$_[$_]+1} 0..3 } DB<118> tst 1..10 => (2, 3, 4, 5)

But your code with reduce didn't work for me, it always returned 0 cause thats the smallest index you passed. 1 cause ...

Could you show us an example and tell us which versions you use?

DB<148> @a= map { int rand 100 } 1..5 => (32, 4, 90, 79, 70) DB<149> sub minindex { reduce { print "@_\t$a:$_[$a],$b:$_[$b]\n"; $ +_[$a] < $_[$b] ? $a : $b } 0 .. $#_ } DB<150> minindex @a CODE(0xa353ea8) 0 1 2 3 4 0:CODE(0xa353ea8),1:0 CODE(0xa353ea8) 0 1 2 3 4 1:0,2:1 CODE(0xa353ea8) 0 1 2 3 4 1:0,3:2 CODE(0xa353ea8) 0 1 2 3 4 1:0,4:3 => 1
