I see what you mean, but that doesn't seem to solve the problem.. Still 
getting the exact same exception... 
To me, it would seem that matching the statement should work *before* getting 
to EOF (after all the statement is complete when the ';' is read), which 
would explain why adding EOF doesn't work here: there is a problem while 
parsing the statement itself (also, the exception mentions that "m" is 
unexpected).
Or could the problem lie with the lookahead? The parser trying to read the 
next 2 tokens but stumbling upon EOF?

I'm a bit lost here...

Thanks,

Hans
