topic forced to be string

[artemk]

Hi guys.
Any reason you force topic to be string?

I have no problem using tuple instead of string, but dialyzer claims because it expect topic to be string.

phash2, which is used inside, accepting term as a first argument. So any reason to force it to be string in lib?

Given different PubSub adapters and potential future features, such as wildcard broadcasts (not planned), it was locked down initially. A future pubsub release will likely open this up to support other terms, but not in the immediate future. Thanks!
