Description

Functions for transforming abstract Haskell code extended with regular patterns into semantically equivalent normal abstract Haskell code. In other words, we transform away regular patterns.

Synopsis

Documentation

transform :: Module -> Module Source

Transform away occurences of regular patterns from an abstract Haskell module, preserving semantics.

transformExp :: Exp -> Exp Source

Transform expressions by traversing subterms. Of special interest are expressions that contain patterns as subterms, i.e. let, case and lambda expressions, and also list comprehensions and do-expressions. All other expressions simply transform their sub-expressions, if any. Of special interest are of course also any xml expressions.
