compileOption

Also remember about how to access the compiler options:

  when compileOption("boundChecks"):  # d:release should disable this.
    if i > q.high:  # x < q.low is taken care by the Natural parameter
      raise newException(IndexError, "Bla has less than " & $(i+1) & " elements.")
  discard

TODO: List them here and how to correctly access the more complex ones.
