Disallow variable names that shadow tags in scope Now, if you have a tag named "foo", a variable declaration like "let foo..." is illegal. This change makes it possible to eliminate the '.' after a nullary tag pattern in an alt (but I'll be doing that in a future commit) -- as now it's always obvious whether a name refers to a tag or a new declared variable. resolve implements this change -- all the other changes are just to get rid of existing code that declares variables that shadow tag names. 2012-01-05 11:46:38 -08:00			`fn main() {`
