bugfix: now dictionaries are deforested correctly again

before:
  _from_to undefined
  _uselect undefined
now:
  StdEnum not imported
  StdArray not imported

using this for accumulators is more elegant than using lists

:: Record = {x :: !Int, y :: Int}
Start = { x = undef, y = 2}.y

has been tranformed into

Start = 2

bugfix in scanner: reals were not treated correctly

of "v314", case defaults and guards now also have file position information.
