In resolve, check that an or-pattern has the same number of bindings in each disjunct resolve3 wasn't checking this. Added test cases. Also added a helpful informational message in the case where you have a variable binding that you probably think refers to a variant that you forgot to import. This is easier to do in resolve than in typeck because there's code in typeck that assumes that each of the patterns binds the same number of variables. 2012-07-10 20:24:41 -05:00			`enum foo { alpha, beta(int) }`

Convert alt to match. Stop parsing alt 2012-08-06 14:34:08 -05:00			`match alpha {`
Switch alts to use arrows 2012-08-03 21:59:04 -05:00			`alpha \| beta(i) => {} //~ ERROR inconsistent number of bindings`
