def Lean.ScopedEnvExtension.setDelimitsLocal {α β σ : Type} (ext : ScopedEnvExtension α β σ) (env : Environment) (depth : Nat) : Environment

Modifies delimitsLocal flag to false on the top depth entries of the state stack, to turn off delimiting of local entries across multiple implicit scope levels (e.g. those introduced by compound namespace A.B.C expansions).

def Lean.stateStackModify {α β σ : Type} (ext : ScopedEnvExtension α β σ) (states : List (ScopedEnvExtension.State σ)) (b : β) : List (ScopedEnvExtension.State σ)

The following function is used to implement end_local_scope command.

By default, all states have delimitsLocal set to true, and the following code modifies only the top element of the stack. If the top element’s delimitsLocal is false, the function instead traverses down the stack until it reaches the first state where delimitsLocal is true. Intuitively, delimitsLocal of each State determines whether local entries are delimited. When set to false, it allows traversal through implicit scopes where local entries are not delimited.
