Variable scope & useless assignments (#41) * AST::Visitor -> AST::NodeVisitor * Scope & ScopeVisitor * Useless assignment rule * Instance vars and useless assignments * Multiple assigns one by one * Support outer scope * Variable used in the useless assignment * Support OpAssign & MultiAssign * Captured by block * Variable, Assignment, Reference & Refactoring * Variable has references, Assignment can be referenced * Branch entity * Handle useless assignments in branches * Handle assignments in a loop * Handle branch equality * Handle special var `$?` assignment * Improve captured by block stuff * Avoid assignments in property definitions (UselessAssign rule reports an warning) * Support MacroIf and MacroFor branches * Handle assignments with shadowed vars in inner scopes * Add method arguments as scope variables * Handle case if branch is blank * Top level scope * Handle case when branch is nop? 2018-05-03 15:57:47 +00:00			`require "../../../spec_helper"`
