#1248 Some tests are not reported as failing

See #1247. It seems AssociativeCollectionTest >> testComma should be failing, but when tests are run, they are all green.

Ok, puzzle solved, I tested something else I thought I did.

(basically, I tested that #{'a'->1.'b'->2},#{'a'->1} equals #{'a'->1.'b'->2} - whole joined with part equals whole, but not that #{'b'->2},#{'a'->1} equals #{'a'->1.'b'->2} (distinct parts joined make the whole).

I'll leave the former as well, but should add the latter, too.

Closing.
