""" Rewrite Rules
|

|
|
|
||
|
|
DISCLAIMER: This module is experimental. The interface is subject to change.

A rule is a function that transforms one expression into another
|
||
|
|
|
||
|
|
Rule :: Expr -> Expr
|
||
|
|
|
||
|
|
A strategy is a function that says how a rule should be applied to a syntax
|
||
|
|
tree. In general strategies take rules and produce a new rule
|
||
|
|
|
||
|
|
Strategy :: [Rules], Other-stuff -> Rule
|
||
|
|
|
||
|
|
This allows developers to separate a mathematical transformation from the
|
||
|
|
algorithmic details of applying that transformation. The goal is to separate
|
||
|
|
the work of mathematical programming from algorithmic programming.
