What are you trying to achieve or the steps to reproduce?

I use joi.types() to extract some types for schema creation.

const {func} = joi.types();

What was the result you got?

undefined

What result did you expect?

function type object

When renaming func to function you intended to keep func as an alias #2012.

At the moment joi.types() returns an object with only function prop in it. An alias here would also be helpful as now I have to do some acrobatics like this:

const {'function`: func} = joi.types();
