#compile(compiler, text) ⇒ Object

Note, this is copied from haml/filter.rb Unless the text contained interpolation, haml seems to naturally cache the result. This was impossible, then to run a test based on session, etc. I removed that check from below.

    # newline so that the whole filter block doesn't take up
    # too many.

TODO: We need to find a way to disable caching
