Decorator Parentheses

A minor nitpick, but all of Typer's decorators require parentheses.

import typer

typer_app = typer.Typer()

# This doesn't work! Missing ()
@typer_app.command
def foo():
    pass

Cyclopts works with and without parentheses.

import cyclopts

cyclopts_app = cyclopts.App()

# This works! Missing ()
@cyclopts_app.command
def foo():
    pass

# This also works.
@cyclopts_app.command()
def bar():
    pass
