+# Why this split:
+
+
+The Module(s) used when evaluating individuals has to be in an external library to make Hint work. so we split the lamda-calculus command program in a library we need to expose in the main library and the implementation.
+
+Sadly, ghc / ghci / cabal can not properly make a public, internal library available to ghci (and, with that, Hint). Should this ever change:
