Components:
* assignments (passive data structure).
Now: just a map from unification vars to types (pb: what about partial types?)
maybe just local assignments (allow only vars as children of pair(α,β))
* constraint propagation: (buch of constraints) → (new constraints * assignments)
* sub-component: constraint selector (worklist / dynamic queries)
* sub-sub component: constraint normalizer: remove dupes and give structure
right now: union-find of unification vars
later: better database-like organisation of knowledge
* sub-sub component: lazy selector (don't re-try all selectors every time)
For now: just re-try everytime
* sub-component: propagation rule
For now: break pair(a, b) = pair(c, d) into a = c, b = d
* generalizer
For now: ?
Workflow:
Start with empty assignments and structured database
Receive a new constraint
For each normalizer:
Use the pre-selector to see if it can be applied
Apply the normalizer, get some new items to insert in the structured database
For each propagator:
Use the selector to query the structured database and see if it can be applied
Apply the propagator, get some new constraints and assignments
Add the new assignments to the data structure.
At some point (when?)
For each generalizer:
Use the generalizer's selector to see if it can be applied
Apply the generalizer to produce a new type, possibly with some ∀s injected

Components:
* assignments (passive data structure).
Now: just a map from unification vars to types (pb: what about partial types?)
maybe just local assignments (allow only vars as children of pair(α,β))
* constraint propagation: (buch of constraints) → (new constraints * assignments)
* sub-component: constraint selector (worklist / dynamic queries)
* sub-sub component: constraint normalizer: remove dupes and give structure
right now: union-find of unification vars
later: better database-like organisation of knowledge
* sub-sub component: lazy selector (don't re-try all selectors every time)
For now: just re-try everytime
* sub-component: propagation rule
For now: break pair(a, b) = pair(c, d) into a = c, b = d
* generalizer
For now: ?
Workflow:
Start with empty assignments and structured database
Receive a new constraint
For each normalizer:
Use the pre-selector to see if it can be applied
Apply the normalizer, get some new items to insert in the structured database
For each propagator:
Use the selector to query the structured database and see if it can be applied
Apply the propagator, get some new constraints and assignments
Add the new assignments to the data structure.
At some point (when?)
For each generalizer:
Use the generalizer's selector to see if it can be applied
Apply the generalizer to produce a new type, possibly with some ∀s injected

(** Preliminary thoughts on ids:
I very much like the simplicity of http://gurno.com/adam/mne/.
5 three letter words means you have a 15 character identity, not actually more
annoying than an IP address and a lot more memorable than the raw digits. This
can be stored as a single integer which is then translated into the corresponding
series of 5 words.
I in general like the idea of having a 'skip' mechanism, but it does need to cost
something so people don't eat up the address space. 256 ^ 5 means you have a lot
of address space, but if people troll by skipping a lot that could be eaten up.
Should probably do some napkin calculations for how expensive skipping needs to
be to deter people from doing it just to chew up address space.
