Binary parameters fail with PyMySQL 1.2.3, 'str' object is not callable

[HardMax71]

With PyMySQL 1.2.3 any query with a bytes parameter fails.

connection.py line 20 imports escape_bytes_prefixed and line 418 calls it. In 1.2.3 that name is not a function any more:

# pymysql/converters.py
# This silly alias is needed for aiomysql compatibility for now. It is scheduled for removal in 1.3.0.
escape_dict = escape_bytes_prefixed = "DO NOT IMPORT THIS!!!"

The alias was added in 1.2.3 to unbreak the import in aiomysql/__init__.py, see PyMySQL/PyMySQL#1274. The import works again, the call doesn't.

Repro:

import asyncio

import aiomysql


async def main():
    conn = await aiomysql.connect(
        host="127.0.0.1", port=3306, user="scott", password="tiger", db="test"
    )
    async with conn.cursor() as cur:
        await cur.execute("CREATE TABLE IF NOT EXISTS t (id INT, data BLOB)")
        await cur.execute("INSERT INTO t VALUES (%s, %s)", (1, b"binary"))
    conn.close()


asyncio.run(main())

  File "aiomysql/cursors.py", line 197, in _escape_args
    return tuple(conn.escape(arg) for arg in args)
  File "aiomysql/connection.py", line 418, in escape
    return escape_bytes_prefixed(obj)
TypeError: 'str' object is not callable

Passes with PyMySQL 1.1.3.

Environment: aiomysql 0.3.2, PyMySQL 1.2.3, MariaDB 13.0.2, Python 3.13.

One more thing: that alias is scheduled for removal in PyMySQL 1.3.0, and escape_dict in aiomysql/__init__.py goes with it. At that point aiomysql won't import at all.
