fromOptionProp gives "Argument of type is not assignable to..." error about monocle-ts HOT 2 CLOSED

@ulyssesp I can't repro

Code

import { Option } from 'fp-ts/lib/Option'
import { Optional } from 'monocle-ts'

interface A {
  readonly a: Option<number>
}

const a: Optional<A, number> = Optional.fromOptionProp<A>('a')

Versions

TypeScript: 3.3.3333

Strange. Manually downgraded to [email protected] which fixed it, and manually upgrading to [email protected] didn't break it.
