I'd like to propose a `&&.` operator which would be shorthand for: ~~~ruby foo && foo.method ~~~ Unlike `&.`, this does not continue the chain if the variable evaluates to `false`. This would give the following result: ~~~ruby false&.class # => FalseClass false&&.class # => false false&.inexisting # => raises NoMethodError false&&.inexisting # => false ~~~ -- https://bugs.ruby-lang.org/ Unsubscribe:
