Prevent should from circumventing target check
Created by: pirj
By directly instantiating expectation handler, should/should_not was circumventing enforce_value_expectation check.
subject(:action) { -> { raise } }
it { should raise_error StandardError }would not print "The implicit block expectation syntax is deprecated", while
subject(:action) { -> { raise } }
it { is_expected.to raise_error StandardError }will.
