It seems now that a call to "template" immediately terminates the route's handling code - no code is executed after calling template (it's not just "return" because it exits multiple function calls").

Example:
==============
sub foo
{
        print STDERR "foo - start\n";
        my $text = template("dummy", {} );
        print STDERR "foo - done\n";
}

sub bar
{
        print STDERR "bar - start\n";
        foo();
        print STDERR "bar - done\n";
}

get '/' => sub {
        print STDERR "before bar\n";
        bar();
        print STDERR "after bar\n";

        return template("index.tt", {} );
};
==================

prints "bar-start" and "foo-start" but never "foo-done" and "bar-done" .

Using "git bisect" (if I used it correctly), this is the first bad commit:

    pass, redirect, forward, halt, send_error, send_file, template now intterupt route workflows (no need to return)

(hehe, after reading the commit message, it's kind of obvious...) .


In any case - is this behavior going to be permanent ?
Meaning: "template" can only be used once, and must be the last statement ?
I can see why it makes sense for "pass", "direct", "send_error" etc. (and probably for most use cases of "template") - but there are exception, like in my case...
