      Shadowing in Scala's for-comprehensions is a nice feature. It has the feel of mutability, but safer, and shadowing's almost always what you want. for { x <- Try(doSomething) x <- mightFail(x) x <- returnTry(x) } yield x Unfortunately it only works with flatMaps, not maps.

      It does, but it doesn't let you insert operations on different values in between.

      But you can still make use of shadowing in for-comprehensions even if you're using `>>=` every place it's possible to.
