Documentation

class Strict lazy strict | lazy -> strict, strict -> lazy where Source #

Ad hoc conversion between "strict" and "lazy" versions of a structure.

Unfortunately all externally defined instances are doomed to be orphans: https://gitlab.haskell.org/ghc/ghc/-/issues/11999 See also https://qfpl.io/posts/orphans-and-fundeps/index.html for
