RE: goto

["Samson, Lyndon (GEIS)" <Lyndon.Samson@...>]

	You are probably best to use goto to get out of an error condition
when in deeply nested code, tagmethods can work
	like exceptions in this case and jump you out.  

	It's unfortunate that 'return' has to be the last statement in a
function, it would be quite useful in these circumstances if it
	could be used anywhere.
