Method: Red::DefinitionNode::Class#initialize

Defined in:
lib/red/nodes/definition_nodes.rb

#initialize(class_name_sexp, superclass_sexp, scope_sexp, options = {}) ⇒ Class

:class, :Foo, (expression), [:scope, (expression | :block)]

> superclass doesn’t show up sometimes when namespaced a certain way; I forgot what the pattern is though
