Unfortunately, statement modifiers cannot be chained. From perlsyn (emphasis in original):

Any simple statement may optionally be followed by a SINGLE modifier, just before the terminating semicolon (or block ending).

In this specific case, you can use grep or map instead, though.

say foreach (grep /test$/, @names);

map { /test$/ and say } @names;

Edit: toolic's remark in Re^2: Concise foreach expression also applies to the above two lines: they'll print the matching @names, not multiple copies of $path_name.
