in reply to How come undef eq '' ??
The earlier excellent answers have already answered your question.
The best description of the why behind Perl context that I have seen is the free Modern Perl book. I encourage you to read the short opening The Perl Philosophy chapter, which contains a clear description of contexts in Perl. Especially note the "Numeric, String, and Boolean Context" section.
