Is it possible to use MLIR dialects?

Hi, I am trying to use MLIR dialects in mojo (other than index), I get unregistered dialect error. Is it possible to register other dialects? Also, is it possible to see generated MLIR?

def main():
    let d = __mlir_attr.`true`
    __mlir_op.`vector.print`[_type=__mlir_type.index](d)

def main():
    let d = __mlir_attr.`true`
    __mlir_op.`vector.print`[_type=__mlir_type.index](d)

error

$mojo guray.mojo
asd.mojo:22:54: error: use of unregistered MLIR operation 'vector.print'
    __mlir_op.`vector.print`[_type=__mlir_type.index](d)

Only index and llvm dialects are shipped/available right now: - https://github.com/modularml/mojo/issues/1064#issuecomment-1766939631 - https://docs.modular.com/mojo/roadmap.html#only-certain-loaded-mlir-dialects-can-be-accessed I haven't seen any way to dump generated MLIR.
