This repo uses Anchor v0.4.4, which is before the constraint = keyword was added. This should fail to compile.

@armaniferrante I was gonna ask. Should I change it to a specific version ?

Nope since that would create an incompatible breaking chnage. The alternative would be to create a branch for the purpose of the anchor test.

@armaniferrante Sure! If you could create a branch for that, and mention the anchor version to bump it to:

I would:

1. Make those changes here, and update this pr to merge to the new branch.
2. Refer to this new branch(in submodule) in the code belonging to Remove depricated: literal constraints solana-foundation/anchor#1441.

Also, if the tests pass here: solana-foundation/anchor#1441 after making these modifications, should that pr merge to master or some new branch ?
