AstVisitor

io.eleven19.krueger.ast.AstVisitor
See theAstVisitor companion trait
object AstVisitor

Utilities for visiting and folding over AST trees.

Traversal uses trampolining (scala.util.control.TailCalls) for stack safety, so arbitrarily deep AST trees can be processed without risk of stack overflow.
