I'll reinforce part of this:  if C++ compilers are our standard, 
Python needn't feel shame about its error-reporting.  While I've
long advocated upgrades to Python's diagnostic-reporting, it's
simply not true that Python points to "no error".  Python reports
a syntax error on a particular line only when there's sufficient
reason.  

I recognize a background with C++ will probably necessitate 
accomodation to Python, because the two do NOT employ the same
style for syntax questions.  Please, though, daniel:  don't make
the mistake of thinking Python's syntax is a mystery.
