Or even direct string interpolation:

>perl -wMstrict -le
"my @stuff = 1 .. 10;
 print qq{interpolate @stuff here};
"
interpolate 1 2 3 4 5 6 7 8 9 10 here

Update: Using something closer to the code of the OP:

>perl -wMstrict -le
"my $stuff = {};
 my $this  = 'here';
 $stuff->{$this} = [ qw(foo bar baz) ];
 print qq{interpolate @{ $stuff->{$this} } here};
"
interpolate foo bar baz here
