No need to double up on the parentheses
(map { $_ => 2 } 'B','C'), (map { $_ => 3 } 'D','E'),

    If we're being nitpicky :) no need to create a lexical block for map:
    $ perl -Mstrict -MData::Dumper -we'my%h=( (map +($_=>2), "B","C","D"), + one=>1 ); print Dumper(\%h)' $VAR1 = { 'one' => 1, 'D' => 2, 'C' => 2, 'B' => 2 };
