Hi,
If unit-test worked like you wanted, your first unit test wouldn't
test much besides "does the quotation I'm testing throw an
exception", because if [ 2 3 + ] somehow returned 7 it would still
pass. So a better unit test would involve checking a known answer,
like [ 5 ] [ 2 3 + ] unit-test.
A way around computing the answer is to do it in the test quotation.
[ t ] [ 2 2 * 2 2 + = ] unit-test
[ t ] [ { 2 3 3 5 6 7 } >ulong-array dup natural-sort = ] unit-test
