Hi,

I'd expect the associative sequence could be constructed and assigned with
another sequence in different order.
But it doesn't work, the src sequence must in the same order as the
dst sequence defined.
E.g. map<pair<K1, int>, pair<K2, int> > cannot take make_map<K2, K1>(1, 2).

This is a bit disappointing :-(

Yep. It's the way it is currently. I might be reworking maps though
so I'll keep this use-case in mind with the update.

Thanks for your attention :)

Now I'm thinking if we could have these:

mapping(dst, src) // all the intersected

left_mapping(dst, src) // requires dst <= src

right_mapping(dst, src) // requires dst >= src

full_mapping(dst, src) // requires equivalence
