I understand that dypgen throws an exception when a syntax error is  
found.

How do I get it to produce line/column numbers when that happens?

It would be rather groovy if the the exception carried  
symbol_start_pos, symbol_end_pos, rhs_start_pos, rhs_end_pos from the  
dyp record since this information is available at the time that the  
exception is raised. A placeholder for a textual message would also  
be very helpful.

A simple error function built into dypgen could then take a message  
and raise the syntax error exception with all the required info.


	Thanks, Joel
