I tend to use this style as well.

I also tend to do my searching inside my editor, so it being on the same line isn't as important for me. If I need to find quickly which file the sub is declared in, I'll do a grep for the sub foo { line, but then I'll open that file in an editor and search for the line. I then have plenty of context on the screen to see above the declaration and below.

Helping get options for ways to document that may help other monks is a good thing, and the discussion has even more ways noted. I'd like to thank everyone who has something constructive to say on how they document their code.
