Thanks.

There are mostly two reasons (be they good or bad). First, BOOST_ASSERT
is not that old. At the time the interval library was designed, there
was no consensus that all the Boost libraries shall use BOOST_ASSERT.
(Is there one now?)
Second, most of the assertions in the interval library are for detecting
invariants internally violated, while BOOST_ASSERT is meant to detect
preconditions a library user did not respect, as far as I understand.
That being said, the assertion in arith2.hpp is precisely meant to
detect a misuse of the library, so this one should be BOOST_ASSERT
actually. Thanks for pointing it out, I will review the various uses of
assert in the new interval library.
Best regards,
Guillaume
