🧑‍💻 Repro

type('string.lower').to('string.trim').to("'success'")('Success')
type('string.lower').to('string.trim').to("'success'")('success ')
type('string.trim').to('string.lower').to("'success'")('Success')
type('string.trim').to('string.lower').to("'success'")('success ')

It appears that the intermediate type does not take effect.

It also seems to happen with pipe:

type('string.trim').pipe(type('string.lower'), type('string'))('Foo ')

I expect this to return 'foo', but it errors instead.
