This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Thrist is a list-like data structure (GADT)
whose elements are values of a two-parameter
datatype. The typing constraint ensures that
the second type parameter of a former value
unifies with the first type parameter of the
latter.
This threading of types is the foundation for
thrists' nice properties. E.g., paired with a
suitable semantics, function composition $(.)$
can be embedded.
Technically a thrist is embodying the concept
of a free category.
Sub-modules demonstrate the power of the thrist
idea by emulating some familiar data structures.
