ruby supplement methods array category core forms effects this:

1.should_equal(1)

update: rather articulate opposite definitions gorilla patching, i only concentration instance above. i have already resolved can't finished few have answered. nonetheless i some-more footnote reason since can't done, maybe feature, accessible python, grant this.

to answer you: reason i might wish simply aesthetics/readability.

 item.price.should_equal(19.99)

this reads some-more english clearly indicates tested value approaching value, ostensible to:

should_equal(item.price, 19.99)
