for-comprehensions without `_ <- x` and without `yield`

[puffnfresh]

This would be cool:

for {
  IO.putStrLn("Hello")
  line <- IO.readLine
  IO.putStrLn(line)
} yield ()

This would be even cooler:

for {
  IO.putStrLn("Hello")
  line <- IO.readLine
  IO.putStrLn(line)
}

👍, somewhat unsurprisingly

[lihaoyi]

This would also be cool

for {
  txt = "Hello"
  IO.putStrLn(txt)
  line <- IO.readLine
  IO.putStrLn(line)
}

but +1 for everything that's been suggested here!

You can already drop the yield, unless you're doing something with your bucket of units.

[NightRa]

Without the yield, it shouldn't necessarily map to unit, it could just do the flatMap's without the final map.
