Sam Tobin-Hochstadt ab3e94b6e2 Add NoFilter and NoObject to represent no information about filter/object. ... Handle these properly in check-below (with test). Use NoFilter and NoObject to make if typechecking work properly with filters. Reject mismatched filters/objects (with test). New version of require/typed that handles opaque and struct requires. Reorganize docs around this. svn: r15155 original commit: 7b82069fa0805e3de16c9a49d6c303789fc75419		2009-06-12 19:04:39 +00:00
