Re: How come undef eq '' ??

in reply to How come undef eq '' ??

For good reasons operators in Perl do type conversions!

==, + - *   and so on do numification so undef is considered 0

eq, . and so on do stringification so undef is considered empty string "".

Anyway using warnings you'll often get "Use of uninitialized value" messages.

I do not understand what your intentions are, but if you wanna test for undef use the designated functions defined or //

EDIT

Equality Operators in perlop

       Binary "==" returns true if the left argument is numerically equal to
       the right argument.
...
       Binary "eq" returns true if the left argument is stringwise equal to
       the right argument.
