enhancement request: introduce expect(object).to(matcher) syntax

[richardwan]

introduce syntactic sugar to make the hamjest code look more like jest code.

__.expect(5).toBe(__.greaterThan(4))

would be equivalent to
__.assertThat(5, __.greaterThan(4))

if this would help people familiar with the "jest syntax" unleash the power of the hamcrest style, i would be happy to try and implement this.
