register_verb not working

[antonio-yu]

The register_verb doesn't work after I update datar to 0.9.1. It worked with olded version.

from datar.all import * 
from pipda import register_verb
from datar.datasets import mtcars
@register_verb
def copy_to_clipboard(df):
    return df.to_clipboard()

mtcars >> copy_to_clipboard()

TypeError: <lambda>() missing 1 required positional argument: 'fun'

@register_verb(DataFrame)
def copy_to_clipboard(df):
  ...
