[_Codemonkeyism]

Sorry for being so confusing

"Even more because your example was pure."

No it wasn't which is the whole point.

    y = x + 1

means

    y = x.map(_ + 1)

by default with async effects.

"same syntax"

Which is also the point, that there is syntax for the effects. When everything is async, there should be no special syntax as you have that syntax all over your code and it's redundant.
