character 'o' not available as data suffix

[GoogleCodeExporter]

What steps will reproduce the problem?
1. compile this snippet:

data ODU :: * where
  Minimal :: ODU
  Next :: ODU -> ODU
 deriving Nat(o)

2. It does compile, but now enter:
prompt> 0o
"keyboard input" (line 1, column 1) tabs []:
unexpected "0" at: "o..."
expecting: end of input, ":", "let", pattern, or expression

3. Observe the error. This does not happen with other letters.

What is the expected output? What do you see instead?

I would expect:

prompt> 0o
0o : ODU

0o01234567 is octal syntax
0x01234567abcdef is hexadecimal syntax

Keys beginning with 'o' and 'x' should be excluded from Nat syntax.
