Re^3: Joining Arrays?

I agree with that. It would be nice if map (and grep) could take a variable like foreach does.

# this doesn't work
my @joined
    = map my $url { map my $code { $url . $code } @codes } @urls;

I guess, but I actually find that version harder to read than the first version. For one thing, it has no indentation options that aren't kind of terrible. For the general, non-nested versions, it might be nicer. `for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";`	[reply] [d/l]

If the map BLOCK is more complicated than [insert personal threshold here], or they are nested I just declare the variable myself. `@joined = map { my $url = $_; map { my $code = $_; $url . $code; } @codes } @urls;` [download]	[reply] [d/l]
