Sorry, I had read whole of them. Now I read and think those are nice,
indeed, once I wrote similar code :) Of course, just Racc is useful.
But for a local variable, such technic cannot be apply because the
scope of a function is different from a local variable. On the other
hand, the current specification on local variable is agreeable at
least for me because it provides clean scope (except for blocks). And
substitute-protection is done on execution whareas we generally expect
to be done statically. So, I consider Racc's way of type-checking is
not enough for practical use.
