With proper indenting it looks a lot better and doesn't need "end foreach"-like comments (if you ever feel you need comments that say what you're ending, fix your style instead!!).

Rule of thumb: always let the thing that causes the indentation be the last on a line. Another rule of thumb: align closing parens/brackets with the indentation of the line that caused indentation.
So don't use:

somefunction(
    foo(bar,
        "Hello World",
       ) // end of foo
            ); // end of somefunction

But instead use:

somefunction(
    foo(
        bar,
        "Hello World",
    )
);

You may or may not like it, but I find it much better readable.

But indeed, Perl is much nicer towards programmers anyway.
