Whatever you meant doesn't apply to both `foreach` and `map`. `foreach` doesn't work well with changing arrays. `map` works well with changing arrays. `foreach` can do what the OP wants, but not well. `map` doesn't do what the OP wants at all.	[reply] [d/l] [select]

Um no. map doesn't like changing arrays either: `#!/usr/bin/perl use Devel::Peek; @a = (1,2); @b = map { pop @a; Dump $_; } @a; $ perl5100 /tmp/p SV = IV(0x9cd41d4) at 0x9cd41d8 REFCNT = 1 FLAGS = (IOK,pIOK) IV = 1 SV = UNKNOWN(0xff) (0x9cd40b8) at 0x9cd4308 REFCNT = 0 FLAGS = ()` [download] Dave.
