Fix dictionaries for SingI. This adds the missing coercions in the constructed evidence for SingI. Previously we simply passed an integer or a string for the evidence, which was not quite correct and causes errors when the core lint is enabled. This patch corrects this by inserting the necessary coercions.

Add the improvement step, for more direct evaluation. Previously we relied on derived constraints to achieve the same, but this is (i) more direct, (ii) using derived constraints delayed evaluation too much, so we ended up interacting constraints that can be solved with existing assumptions, which may lead to non-termination because it generates infinitely many useless constraints.

8:13 AM Changeset in base [040313e]data-proxydbcsghc-7.8type-reasoning by Joey Adams <joeyadams3.14159@…>
BufferedIO: fix bug in writeBufNonBlocking introduced by commit 7d39e100 bufferAdjustL does nothing but update bufL, and set bufL = bufR = 0 when bufL == bufR. It ignores the old bufL. writeBufNonBlocking is currently unused. It is only used to implement flushWriteBuffer0, which is never called by base (hPutBufNonBlocking uses a blocking flush).

5:05 AM Changeset in ghc [f557bf3]type-nats by Iavor S. Diatchki <iavor.diatchki@…>
Fixes to restore proper operation of widening function. We need to be careful when we use BRules in interaction: unlike axiom rules, using them does not always result in useful information---in fact often it results in trivial facts. Furthermore, we have to be careful not to disable an interaction with an existing assumption (i.e., if we apply a rule to bRule, we should also keep a copy around in case the same slot might be filled by an assumption). At present, we only interact the BRules after we've tried all assumptions: this reduces the number of useless facts we construct, but is sufficient for the main use case of interacting with BRules, namely improvements of the form: a + 0 ~ b => a ~ b.
4:59 AM Changeset in ghc [240cd84]type-nats by Iavor S. Diatchki <iavor.diatchki@…>
