### 1160. `future_error` public constructor is 'exposition only'

Addresses UK 331

Description

Not clear what it means for a public constructor to be 'exposition only'. If the intent is purely to support the library calling this constructor then it can be made private and accessed through friendship. Otherwise it should be documented for public consumption.

Suggestion

Declare the constructor as private with a note about intended friendship, or remove the exposition-only comment and document the semantics.

Notes

Create an issue. Assigned to Detlef. Suggested resolution probably makes sense.
