Class: Riml::AST_Rewriter::SplatsToCallFunctionInCallingContext

Inherits:
Riml::AST_Rewriter show all
Defined in:
lib/riml/ast_rewriter.rb

Overview

Rewrite constructs like:

let animalObj = s:AnimalConstructor(*a:000)

to:

let animalObj = call('s:AnimalConstructor', a:000)

Basically, mimic Ruby’s approach to expanding lists to their constituent argument parts with ‘*’ in calling context.
