trait CanBindLocals[R] extends AnyRef
Type class describing how Local binding works for specific data types.
This is needed because asynchronous data types, like Future,
that can be waited on, should also clear the modified context
after completion.
NOTE: this type class does not work for data types that suspend the
execution, like Coeval or Task, because Local is meant to
be used in a side effectful way. Instances of this type class
can't be implemented for data types like Task, as a technical
limitation, because Task would also need a suspended Context
evaluation in bindContext.

- @implicitNotFound("""Cannot find an implicit value for CanBindLocals[${R}].
If ${R} is the result of a synchronous action, either build an implicit with
CanBindLocals.synchronous or import CanBindLocals.Implicits.synchronousAsDefault.""")
