 # --- Undocumented/Internal Symbols ---

-# These symbols are present in the runtime gmpy2 module but are not
-# part of the documented public API in version 2.2.1. Stubs focus on
-# the documented API. Including them here prevents stub checker errors
-# for symbols users shouldn't typically rely on directly.

-# 'numer' and 'denom' exist as properties on mpq/mpz/xmpz, but these
-# function-like entries likely correspond to internal accessors or
-# older/deprecated ways of access not in the current documentation.

-gmpy2.numer

-# These functions appear related to older gmpy versions or internal binary formats
-# and are not documented for current use.

+# These were previously allowlisted based on errors likely caused by

+# When comparing against the top-level gmpy2 module, these are not found,
