This seems reasonable but it still results in significant yet unquoted 
whitespace which I abhor.  Maybe you could also allow an explicit 
escaped newline like this for neat-freaks like me.

<if(LEXER)>
      System.err.println("<description>: no viable alt line "+getLine()+"
c='"+(char)input.LA(1)+"'");<\n>
<else>
      System.err.println("<description>: no viable alt line
token="+((TokenStream)input).LT(1));<\n>
<endif>

And yes, I agree that python is awesome. But nevertheless...
