Dear Haskellers,
I'd like to announce a small library "tie-knot":
"Ties the knot" on a given set of structures that reference each other by
keys - replaces the keys with their respective values. Takes Map k (v k)
and converts into Map k v' where v' is the fixed point of v.
Motivation: I needed to assemble a finite-state machine from an
external description where each node was described by some identifier. I
needed a simple library that would replace all key referencess with the
actual values.
See https://github.com/ppetr/tie-knot for examples.
