For example: (1) NODE_MASGN * NODE_SPECIAL_NO_NAME_REST ``` $ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("a, * = b").children[-1].children' [#<RubyVM::AbstractSyntaxTree::Node:VCALL@1:7-1:8>, #<RubyVM::AbstractSyntaxTree::Node:ARRAY@1:0-1:1>, :NODE_SPECIAL_NO_NAME_REST] ``` (2) NODE_POSTARG * NODE_SPECIAL_NO_NAME_REST ``` $ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("a, *, _ = b").children[-1].children[-1].children' [:NODE_SPECIAL_NO_NAME_REST, #<RubyVM::AbstractSyntaxTree::Node:ARRAY@1:6-1:7>] ``` (3) NODE_LASGN * NODE_SPECIAL_REQUIRED_KEYWORD ``` $ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("def a(k:) end").children[-1].children[-1].children[1].children[7].children[0].children' [:k, :NODE_SPECIAL_REQUIRED_KEYWORD] ``` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67627 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | * ast.c: I created a new C source code file with tabs and spaces mixed format by mistake. Currently we move to spaces only. Surely we agreed not to batch update. But ast.c is a new source code. So please forgive me to change the format before many changes are committed this file. I'm sorry about my mistake. ref [Bug #14246] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63586 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
