# It's where you hide your "assertions".
#
# Please note, because of the way that expectations are implemented,
# all expectations (eg must_equal) are dependent upon a thread local
# variable +:current_spec+. If your specs rely on mixing threads into
# the specs themselves, you're better off using assertions or the new
# _(value) wrapper. For example:
#
#     it "should still work in threads" do
#       my_threaded_thingy do
#         (1+1).must_equal 2                  # bad
#         assert_equal 2, 1+1                 # good
#         _(1 + 1).must_equal 2               # good
#         value(1 + 1).must_equal 2           # good, also #expect
#         _ { 1 + "1" }.must_raise TypeError  # good
