DoCodegenFallbackHandler

class DoCodegenFallbackHandler extends LambdaCompilationHandler

Defaults to calling codeGen, this can either be an original compilation approach or the CodegenFallback depending on implementation. It will evaluate the entire tree of expr and return all NamedLambdaVariables as they will not be using the same compilation approach.

This is the default for known OSS implementations and should also be used if compilation will not be within the same class
