Would it be possible for a normally fatal program error to be
converted to a throw, and then be caught?

Would you code the catch statement before or after the call?
I only mention that as I suspect you might have difficulty finding a
catch statement at top level if it is coded after(?). Either way I
would expect:

	catch (sequence s)
	  <statements only executed after thrown exception caught>
	end catch
	<processing continues here>

Is that about right?
