Hi,

I'm trying to check if a given value is a function, but I'm getting the following error:

Using the is.function_ does work, but if this is expected I think we should update the README which also uses the function instead of function_: https://github.com/sindresorhus/is#functionvalue

Similarly with other types like null_ or class_.

It's a TS limitation only. I have documented it better now: https://github.com/sindresorhus/is/commit/04ccf21dba99e9c07c41a38bcf3e4881c06b1bac
