Special 'of' macro syntax doesn't parse

[ddlsmurf]

From the manual:
import macros
macro case_token(n: stmt): stmt =
# creates a lexical analyzer from regular expressions
# ... (implementation is an exercise for the reader :-)
nil

case_token: # this colon tells the parser it is a macro statement
of r"[A-Za-z_]+[A-Za-z_0-9]*":
  return tkIdentifier
of r"0-9+":
  return tkInteger
of r"[\+\-\*\?]+":
  return tkOperator
else:
  return tkUnknown

Doesn't parse with:
Hint: used config file '/Users/eric/Documents/Private/Code/nimrod/Compiler/Nimrod/config/nimrod.cfg' [Conf]
Hint: system [Processing]
Hint: test [Processing]
Hint: macros [Processing]
Error: test.nim(8): expression expected, but found '[same indentation]'
