Re^4: Experimental warnings with given/when

[ikegami]

what's stopping them is the huge table of cases.

That could very well be part of it, but the main reason (in my mind) is the fact that the table treats two (stored as a number) differently than two (stored as a string). This leads to surprises/problems because the rest of Perl doesn't tend to distinguish how something is stored. This means the operator is broken-by-design.
