Please accept PEP 649! Python's type hinting has become so much more useful than originally thought, and without this change much of that will be hindered. For example (you already know about Pydantic and FastAPI) [discord.py](https://github.com/Rapptz/discord.py)'s commands system allows you to use typehinting to specify how arguments should be converted. Take the following code: ```py import discord from discord.ext import commands bot = commands.Bot(command_prefix='>') @bot.command() # discord.py reads the typehints and converts the arguments accordingly async def reply(ctx, member: discord.Member, *, text: str): # ctx is always passed await ctx.send(f'{member.mention}! {text}') bot.run('token') ``` I must say, this is extremely ergonomic design! Don't break it :)
