WeekDaze.Identifiers.TimeslotId

AUTHOR

Dr. Alistair Ward

DESCRIPTION

Defines a suitable type for its polymorphic namesake.

CAVEAT

Exporting nothing but the type-constructor forces this to be used only as an interface, & therefore to be easily replaced; though a data-constructor is also exported for testing.
