class Opal::Nodes::Args::ExtractOptargNode
Compiles extraction of a single inline optional argument def m(a = 1); end
^^^^^
This node doesn’t exist in the original AST
, InlineArgs rewriter creates it to simplify compilation
Sometimes the argument can’t be inlined. In such cases InlineArgs rewriter replaces
s(:optarg, :arg_name, ...default value...)
to:
s(:fakearg) + s(:extract_post_optarg, :arg_name, ...default value...)
