Description

As per: Equivalence of two Literals

Two types Literal[v1] and Literal[v2] are equivalent when both of the following conditions are true:
type(v1) == type(v2)
v1 == v2

I would like to update deserialization for typing.Literal in v1 opt-in to account for this.

Perhaps a Meta setting strict_mode_for_literals: bool, or else more simply a strict: bool, can be added to support this feature / enhancement.

Research direction

Start by locating the v1 opt-in deserialization path for typing.Literal and the Meta configuration described in the issue. Compare the current behavior with the typing specification's equivalence rules, then determine the configuration shape and add coverage demonstrating strict and non-strict literal handling.
