Sometimes easier said than done. For instance look at I refuse to explain this. The reason for said refusal is that Dominus literally did not know how to explain it.

Incidentally "saint level" refers to participation on the site, and not Perl knowledge. For instance TheDamian may not be a saint (OK, so he seems to work for the Other Side, details), but certainly knows more Perl than the vast majority of the people in Saints in Our Book.
