Syntax coercions do not need to be the identity. See for example
``Coe (TSyntax `ident) (TSyntax `declId)``.

fix: replace dangerous instance by CoeTail
...
In order to guarantee termination of type class synthesis when resolving
coercions, a good rule of thumb is that the instances should not
introduce metavariables (during TC synthesis). For common coercion type
classes this means:
- `Coe T S`, `CoeTail T S`: the variables of `T` must be a subset of those of `S`
- `CoeHead T S`: the variables of `S` must be a subset of those of `T`
If these rules are not followed, we can easily get nontermination. In
this case: `CoeTC Foo Syntax` is reduced to `CoeTC Foo (TSyntax ?m_1)`
using the (dangerous) `Coe (TSyntax k) Syntax` instance, to which we can
then apply the otherwise fine `Coe (TSyntax [k]) (TSyntax (k'::ks))`
coercion infinitely often.

feat: improve isDefEq for projections
...
When solving `a.i =?= b.i`, we first reduce `a` and `b` without using
delta reduction. If at least one become a structure, we reduce the
projection. Otherwise, we try to solve `a =?= b`, only reduce `a.i`
and `b.i` if it fails.
