Subject.isIn(Iterable<?>) (and/or varargs) about truth HOT 4 CLOSED

I have a usecase for this method, too (a method allowed to return a specific number either as Integer/Long/BigInteger). I would name it isEqualToAnyOf (to be consistent with isEqualTo) and prefer the varargs form.

I also propose to add isNotEqualToAnyOf. Recently I was writing a test in a parameterized test suite which should only be executed for 3 out of 5 values of some enum parameter, so I want to blacklist 2 of the enum values with

assume().withFailureMessage(subject + " does not support feature X")
    .that(subject).isNotEqualToAnyOf(MyEnum.Val1, MyEnum.Val4);

from truth.

I also have a use case for this method. isEqualToAnyOf is a bit verbose in my opinion, something like isOneOf or isAnyOf for the varargs version would be good (although I don't have strong feelings about the name). isIn or isContainedIn would be good names for the Collection version. isContainedIn matches the Collection#contains.

from truth.

I have a fix for this in flight.

from truth.

For the record, we're going with the following API:
isIn(Iterable) / isNotIn(Iterable)
isAnyOf(first, second, rest...) / isNoneOf(first, second, rest...)

from truth.
