Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Normally, we evaluate the matching sequentially. For an expression like ‘expect(x).to foo.and bar`, this becomes:

expect(x).to foo
expect(x).to bar

For block expectations, we need to nest them instead, so that ‘expect { x }.to foo.and bar` becomes:

expect {
  expect { x }.to foo
}.to bar

This is necessary so that the ‘expect` block is only executed once.
