Come to think of it:

foreach ( @alist ) {
    if ( condition( $_ ) ) {
      do_something( $_ );
    }
}

[download]

can be written as

foreach ( @alist ) { condition( $_ ) and do_something( $_ ) }

[download]

Which is as pretty as the map version. The point about worrying too much about memory still stands though.

Have Fun
