This PR changes the "declaration uses 'sorry'" warning to use backticks instead of single quotes, consistent with Lean's conventions for formatting code identifiers in diagnostic messages.

error: failed to synthesize instance of type class

OfNat α 22
|
||
numerals are polymorphic in Lean, but the numeral `22` cannot be used in a context where the expected type is
|
||
α
|
||
due to the absence of the instance above
|
||
|
||
Hint: Type class instance resolution failures can be inspected with the `set_option trace.Meta.synthInstance true` command.
