Re^2: Expression form of map or grep

[AnomalousMonk]

I think @list will not contain anything from @grey_scale, and would warn with something like "Useless use of private array in void context" ...

Ah, good catch!

c:\@Work\Perl\monks\Lady_Aleena>perl -wMstrict -MData::Dump -le
"my @colors = qw(a b c);
 my @grey_scale = qw(x y);
 my @list = map( qq{$_ beads}, @colors ), @grey_scale;
 dd \@list;
"
Useless use of private array in void context at -e line 1.
["a beads", "b beads", "c beads"]

Another set of parentheses is needed to include the second (and any subsequent) array:

c:\@Work\Perl\monks\Lady_Aleena>perl -wMstrict -MData::Dump -le
"my @colors = qw(a b c);
 my @grey_scale = qw(x y);
 my @list = (map( qq{$_ beads}, @colors ), @grey_scale);
 dd \@list;
"
["a beads", "b beads", "c beads", "x", "y"]
