Has anyone experimented with trying to combine pre-existing grammars? That is, copying two programs into one and then linking their rules together in various ways?
I was subjecting some of the example grammars to this approach this morning. Unsurprisingly, mixing things up without thinking about it much tends to generate a total mess less interesting then either of its parts, though I'm sure some interesting hybrids could be created with some attention and cleverness.
Something I look forward to playing with again soon, but I thought I would put it out there to the community in the meantime.
mashups, dare I say it
