in thread grep instead of foreach?

is using a hash-slice there. The idea is: to address more then one entry in the hash at once. a simple example:
my %languages; $languages{'python'} = 'boring'; @languages{'perl', 'perl6'} = ('cool', 'real soon now'); # this is short for ( $languages{'perl'} , $languages{'perl6'} ) = ('cool', 'real soon now'); # or $languages{'perl'} = 'cool'; $languages{'perl6'} = 'real soon now';

There are also array-slices.

Read perlman:perldata
