Re: removing the old-style package separator
Message ID:
I've very occasionally used Test::More::isn't * -- and I would not mind at
all to change these uses to Test::More::isn_t or ::isnt.

* it isn't (ha!) actually all that useful because normally you want to know
what something *is*, and if it *isn't* a value, it isn't necessarily what
you want it to be (this is the same as why "I got an exception" is a
terrible test -- you really should check that you got the *right*
exception, as it could just as easily be "syntax error in your code" which
ought to result in a failing test) -- so uses are better off changed to
is() or perhaps like().
