The recover tactic modifier

This defines the recover tactic modifier, which can be used to debug cases where goals are not closed correctly. recover tacs for a tactic (or tactic sequence) tacs applies the tactics and then adds goals that are not closed, starting from the original goal.

def Mathlib.Tactic.getUnassignedGoalMVarDependencies (mvarId : Lean.MVarId) : Lean.MetaM (Std.HashSet Lean.MVarId)

Get all metavariables which mvarId depends on. These are the metavariables which occur in the target or local context or delayed assignment (if any) of mvarId, plus the metavariables which occur in these metavariables, etc.
