I'm using a custom perl script in the following way:

location ~ ^/resources {
error_page 404 @fallback;
}

location @fallback {
perl MyModule::handler;
}

The fallback works as expected, apart from that it always returns a 404
with content, rather than a 200.

Is there any way to force a 200 when I'm sending content back to the
browser from either the Perl script or from the @fallback block?
