You could try wheeling out Haskell's Least Used Keyword:

    module Defs where

    default(Double, Int)

    n = 3       -- This is defaulted to Double
    x = 12.3

    test = ceiling (x / n)

Other than that, I only know an answer that starts with "Design and
implement a language extension for ...", sorry.
