Module mz_transform::normalize
source · Expand description
Normalize the structure of Let and LetRec operators in expressions.
Normalization happens in the context of “scopes”, corresponding to
- the expression’s root and 2. each instance of a
LetRecAST node.
Within each scope,
- Each expression is normalized to have all
Letnodes at the root of the expression, in order of identifier. - Each expression assigns a contiguous block of identifiers.
The transform may remove some Let and Get operators, and does not
introduce any new operators.
The module also publishes the function renumber_bindings which can
be used to renumber bindings in an expression starting from a provided
IdGen, which is used to prepare distinct expressions for inlining.
