30fa93ab4e refactor core syntax slightly to derive Eq/Show
add a new `WithSubst tm env to` record that packages a `tm from`
with a `Subst env from to`, and write instances for just that. the
rest of the AST can be derived

7e079a9668 add file locations to Parser.Syntax
they're immediately thrown away currently. but one step at a time

b74ffa0077 rewrite parser
previously it backtracked too much, so instead of giving a useful
parse error, it just said "expected end of input" at the beginning of
the problem toplevel. which, if it's a namespace, could be way off.

a4ffd74625 fix the most embarrassing quantity mistake ever 2023-04-20 19:29:57 +02:00

e.g. "(x y : ℕ) × plus x y ≡ 10 : ℕ"

4db373a84f use constraints when checking δ
when checking δ 𝑖 ⇒ s, add 𝑖=ε to Ψ instead of checking s‹ε/𝑖›.
this has the same effect but an error message will show "𝑖, 𝑖=ε" in
the context

3fb8580f85 re-add tightening and use it when messing with scopes
e.g. "coe [_ ⇒ A] @p @q s" should immediately reduce to "s",
but if the "_ ⇒ A" happened to use an SY it didn't.

this will still happen if a wrong SY sneaks in but the alternative is
re-traversing the term over and over every time whnf runs

773f6372ea quantities in case don't need to be *exactly* the same
...as long as they are all compatible with the target.
for example, given ω.n : ℕ:
```
  case double_it? return ℕ of {
    'true  ⇒ plus n n;
    'false ⇒ n
  }
```
