load-table's annotation is unused

[sorawee]

Following is from the documentation:

import gdrive-sheets as GS
import data-source as DS

imported-my-table =
  GS.load-spreadsheet("1BAexzf08Q5o8bXb_k8PwuE3tMKezxRfbKBKT-4L6UzI")

my-table = load-table: name :: String, age :: Number, favorite-color :: String
  source: imported-my-table.sheet-by-name("3-rows", true)
  sanitize name using DS.string-sanitizer
  sanitize age using DS.strict-num-sanitizer
  sanitize favorite-color using DS.string-sanitizer
end

If I change String to Number, everything still runs fine.

This is complicated, and after talking it over with Joe, we're going to defer this for a (probably good long) while.
