Ummm, it can't catch errors if it's not used, I would think...
The use of custom types is a valid way of programming, and having an
interpreter and a translator looking at the code differently is an 
error, no matter how you justify it.

Ok, to type check custom types every time a value is assigned is going
to slow things down a little, so perhaps if the programmer explicitly declares
'with type_check' then it will...

Also Pete, each of your instances of

type db_error(integer s)
	if 
	---stuff
	return 1
end if

err = db_function(arg, arg2, arg3)

could be replaced with

type db_error(integer s)
	if 
	---stuff
	return 1
end if

if db_error( db_function(arg, arg2, arg3) ) end if


or something similar...
