brian_d_foy,
Yes,
pos and
next are both Perl keywords. I am
currently ambivalent on both points you raise. I could make the argument that there is enough visual distinction between a method call and a built-in call not to confuse the two or that shortened names for things have thrived in Unix for years, but I won't.
You have much more experience writing software for others than I do so I will take your advice. There were comments made by diotalevi and others in the CB that I will take as well. I solicited comments because I don't do this for a living ;-)
