434c33f225 feat(metavar): automatically apply beta-reduction when instantiating metavariable applications (i.e., expressions of the form (?m a)), when the metavariable is a lambda
This feature is useful for problems that require higher-order matching and/or unification.

- Avoid confusion with util/trace.h
