A question about that. With the way those tests are made, one can only
compare numerical values at compile time, which means all array tests
are either a call to ARRAY_ELEM, ARRAY_SIZE or ARRAY_IS_EMPTY. I'd
like to find a way to write tests that compare entire arrays / tuples.
A naive way to do that would be to STRINGIZE the arrays and compare
the resulting strings at runtime.

However, it seems to me that doing runtime checks would be a big
change to the way BOOST_PP is currently tested, and I'd like your
opinion on that subject before doing anything.
