You don't need to cast the =~ operator's return value to boolean with !!. The ternary operator will work fine with the nil or number it returns.
Not every ruby developer agrees, but I avoid using !! to cast to boolean unless strictly required (like when serializing to JSON). Some ruby devs think predicate methods (like #foo?) should only return true or false, but Ruby's core and stdlib don't behave that way. ¯\_(ツ)_/¯
