libsyntax-operator-equ-perl - 0.10-1+b1 main

Syntax::Operator::Equ provides infix operators that implement equality tests
of strings or numbers similar to perl's eq and == operators, except that they
consider undef to be a distinct value, separate from the empty string or the
number zero.
.
These operators do not warn when either or both operands are undef. They
yield true if both operands are undef, false if exactly one operand is, or
otherwise behave the same as the regular string or number equality tests if
both operands are defined.
