S29 doesn't document .trim, but like other similar methods I
would expect it to be defined on C<Any>. If so, I would
expect the output of the above to be C< ["foo bar"]\n >.

I would expect this to be roughly equivalent to:
for @array { $_ .= trim; }
For an array of hashes, this would result in each hash element
of @array being replaced with a reference to an array of the
trimmed string representation of the hash.
