        If the 'sub' argument matches the regular expression /^\s*sub[^\w:]/, it
        is assumed to be a subroutine reference. Otherwise it's assumed to be
        the name of a function. In the latter case, the string "main::" will be
        prepended to the function name if the name doesn't contain "::" (this
        forces the function to be in the main package, or a package you
        specify). Note that it's a pretty bad idea to put your code in the main
        package, so I only halfheartedly endorse this feature.

        In general, it will be slower to use anonymous subroutines, because each
        one has to be eval()'ed and there is no caching. For best results,
        pre-load any code you need in the parent process, then call it by name.

        If you're calling a subroutine like "&Package::SubPack::handler", you
        can omit the "handler" portion, making your directive like this:

         <!--#perl sub="Package::Subpack"-->

        If you want to supply a list of arguments to the function, you use
        either the "arg" or the "args" parameter:
