This looks to be functionally equivalent to the FeatureMatcher class.

Although I prefer the idea of composing this functionality from a Function and Matcher as you have done, I'm not keen on defining a Function type in Hamcrest. There are already many incompatible definitions of Function in the Java world. Until Hamcrest supports Java 8 I'd rather this functionality was implemented as an adaptor library that let you use, say, Guava's Function type.

Postponed until Hamcrest supports Java 8. Until then, should be an auxiliary library.

I've released Hamcrest Compose which provides a hasFeature matcher along these lines.
