> This traces into code that attempts to load the first argument (argument 0,
> as Plastic numbers them) which fails because the method contains no
> parameters. A better case would be to check that each method takes at least
> one parameter, and preferably, find a way to ensure that the first parameter
> is the correct selector type.
