> It is all too easy to write assert(foo, bar) when you meant to write assert_equal(foo, bar). I have made the same mistake myself a number of times. Usually, no error will result because assert allows an optional second parameter (an alternate String to be printed when the assertion fails).

Yeah something like that could work well.  When would someone want to
output something that's not a string?
