and don't add them, and you have a linear amount.

then why did you provide CHECK_EQUAL ? Afterall, it can be done with
the generic tool.

surely it wouldn't be too hard to write first hand tools for ==, !=, <, <=
to give users the most pleasent experience ? (> and >= is not needed as we can 
reverse the arguments)
