Is there a way to try experimental opcodes?

I’d like to experiment with the bn256_* opcodes. Is there a way to use them by using the sandbox or do I need to build algod from source?

If building is the only way, is it safe to just set the LogicVersion to 9?

Note that these opcodes may change in the future.
But you normally should be able to experiment using sandbox and the source configuration:

./sandbox up source

after updating config.source to point to the branch of your choice (currently develop).
