I'm sorry, but which grammar rules in Perl 5 are inconsistent? I've taught Perl 5 professionally, and while I certainly do acknowledge that Perl isn't optimal for learning, "inconsistent grammar" is not on my list. It does have a more-complex grammar than, say, lisp, but it's still an extremely consistent grammar, as far as I've been able to tell. I also disagree with the claim that a large vocabulary in Perl is a notable issue. The size of the Perl grammar and language is sufficiently smaller, in my experience, than the size of all of the library APIs that I have to deal with when writing Perl programs.
