Example Code

import typer
from typing import Annotated
app = typer.Typer()
user_app = typer.Typer()

@user_app.command("create")
def create_user(a_boolean: Annotated[bool,
        typer.Option(
            default=False,
            help="Help string stufff ....",
        )]):
    print("did something")

app.add_typer(user_app)

if __name__ == "__main__":
    app()

Description

Hi, running the above script raises AttributeError: 'bool' object has no attribute 'isidentifier'

This is caused by the default=False option in the Option.
I use click 8.1.7, and this one works fine:

import click

@click.command()
@click.option("--mybool", default=False, help="Number of greetings.")
def hello(mybool):
    print("test", )

if __name__ == '__main__':
    hello()

Also, when I set the default value directly as a default argument it does works :

@user_app.command("create")
def create_user(a_boolean: Annotated[bool,
        typer.Option(
            help="Help string stufff ....",
        )] = False ):
    print("did something")

app.add_typer(user_app)

if __name__ == "__main__":
    app()

The docs says that default is supported, but it seems to works with strings, but not with bool.
