So? What's the problem if this case needs calc()? How is calc() a hurdle?
I think calc(10%+5px) calc(10%+5px) is *much* more readable than 10% 5px 10% 5px, which I had a really hard time figuring what you expect it to do (and I'm still not sure I got it right).

  Nor does it allow things like "10%
> bottom 5px" to mean "10% calc(100% - 5px)".  "[ left | right |
> <percentage>  ] [<length>  ]?" would make more sense to me than "[ left
> | right ] [<percentage>  |<length>  ]?".  But that's a side point.)

You can write left 10% bottom 5px, which isn't very far from what you wrote. Five extra characters aren't such a big problem, and they help readability too.
