Things like (,) () aren't straightforward IVar's but are IAlternative's
which present options about how the term should resolve. [| |] was not
accounting for this.
useful items for applying multiple predicates, e.g.
sortBy (comparing length <+> compare)
To sort some lists elements by length and then lexographically
`Core.Context` is 2k+ LoC and contains a *lot* of different thins.
Rather than moving the `log` functions above of `addData` to be able
to add logging there, fork them off to independent files to make the
whole thing more readable.
Nipping this historical artifact in the bud before it roots. It's often
useful to be able to `map` directly to the result of a StateT computation
and due to how Functor works this is made harder when the tuple is
(a,state) vs (state,a)
* [contrib] Add misc libraries to contrib
Expose some `private` function in libs/base that I needed, and seem like
their visibility was forgotten
I'd appreciate a code review, especially to tell me I'm
re-implementing something that's already elsewhere in the library
Mostly extending existing functionality:
* `Data/Void.idr`: add some utility functions for manipulating absurdity.
* `Decidable/Decidable/Extra.idr`: add support for double negation elimination in decidable relations
* `Data/Fun/Extra.idr`:
+ add `application` (total and partil) for n-ary functions
+ add (slightly) dependent versions of these operations
* `Decidable/Order/Strict.idr`: a strict preorder is what you get when
you remove the diagonal from a pre-order. For example, `<` is the
associated preorder for `<=` over `Nat`.
Analogous to `Decidable.Order`. The proof search mechanism struggled
a bit, so I had to hack it --- sorry.
Eventually we should move `Data.Fun.Extra.Pointwise` to `Data.Vect.Quantifiers` in base
but we don't have any interesting uses for it at the moment so it's not
urgent.

There's some missing flexibility in how foreign specifiers can be used with
scheme that is addressed here with minimal changes to how scheme specifiers
are read. This opens up uses for users that they otherwise would have had
to modify the compiler's support files to accomplish.
