## Instances For

Adds a type annotation to a hole that occurs immediately at the beginning of the term. This is so that coercions can trigger when elaborating the term. See https://github.com/leanprover/lean4/issues/2040 for further rationale.

`_ < 3`

is annotated`(_) < 3`

is not, because it occurs after an atom- in
`_ < _`

only the first one is annotated `_ + 2 < 3`

is annotated (not the best heuristic, ideally we'd like to annotate`_ + 2`

)`lt _ 3`

is not, because it occurs after an identifier
