Thanks for the heads up.

I *had* to try the Python one as it will be very useful at work !! :)  I 
noticed the following, but won't have time to look into it much until after 
the holidays.  Nevertheless, here's what I found:

$ /usr/local/bin/antlr -traceLexer tinyc_l.g
ANTLR Parser Generator   Version 2.7.5rc1 (20041222)   1989-2004 jGuru.com
tinyc_l.g:41: warning:lexical nondeterminism upon
tinyc_l.g:41:     k==1:'*'
tinyc_l.g:41:     k==2:'/'
tinyc_l.g:41:     between alt 1 and exit branch of block

$ /usr/local/bin/antlr -traceParser tinyc_p.g
ANTLR Parser Generator   Version 2.7.5rc1 (20041222)   1989-2004 jGuru.com
tinyc_p.g:99:17: warning:nondeterminism between alts 1 and 2 of block upon
tinyc_p.g:99:17:     k==1:"else"

$ python tinyc_p.py < tinyc.in
Traceback (most recent call last):
  File "tinyc_p.py", line 676, in ?
    P.program()
  File "/home/kibab/antlr-2.7.5rc1/examples/python/tinyc/tinyc_p.py", line 55, 
in program
    self.traceIn("program")
  File "/usr/lib/python2.3/site-packages/antlr/antlr.py", line 1606, in 
traceIn
    self.trace("> ", rname)
  File "/usr/lib/python2.3/site-packages/antlr/antlr.py", line 1590, in trace
    self.traceIndent()
AttributeError: 'Parser' object has no attribute 'traceIndent'

And, when I don't build with -traceLexer or -traceParser:

$ python tinyc_p.py < tinyc.in
stop - no AST generated.

Hence, that's why I turned on traceLexer and traceParser.  It's possible it's 
in the docs and I missed it as I won't have time to read them until after the 
holidays ;)

Finally, thank you for your work on this!  I want[ed?] to be a part of the 
antlr-3 Python port, but was waiting to hear that Terence was ready to get 
started on it more.

Thanks.
