Hi, I oftenly use `Numeric#nonzero?'. Actually, I miss its equivalent, a method maybe `String#notempty?', returning the string if it has a length and nil otherwise. It wasn't difficult to write and it's not using much space: http://www.bertram-scharpf.de/tmp/notempty.patch Do you think it is worth being included?
