253	Improve syntax exception reporting	Stephen Siegel	bperry	"There is a nice SyntaxException class, but it is not used in many many places in the front end.   Instead, various runtime exceptions are thrown and the error reports are often cryptic.

Someone needs to go through the whole front end and check that all syntax exceptions are dealt with in a common way : throwing a SyntaxException with a non-null Source info and good, clear message.   The exceptions are caught up in the verify module and reported correctly."	defect	closed	major	1.1	front	1.1	fixed	syntax exception error reporting
