assertNot(L, R)

[xaviergonz]

it would be cool to have a negative assertion that ensures that a given L type does NOT conform to R type

e.g.

assert("hi", _ as "hi") // compiles ok
assert("bye", _ as "hi") // compilation error

assertNot("bye", _ as "hi") // compiles ok
assertNot("hi", _ as "hi") // compilation error

That way it can negative cases could be more easily integrated into jest without too many modification (just by expecting "ok" compilation cases for assertions and not assertions)
