I have two questions, but the second may not be necessary depending on the answer to this first one; in Spirit2, when creating grammars that include other grammars (that include others and so on and so forth), is it better to construct them in the grammar itself (like any other rule), or is it better to have, say, a singleton of it somewhere and link that in, and if a singleton then would it be thread-safe?

...r small RegExes but it wouldn't do so well for more elaborate and long expressions. If what you need is something for a short regex, a packrat algorithm will do fine. A 256-character string may bloat up to a couple of KB and still be reasonably cheap. If you're looking for a full parser, Spirit2.x might be better. --Sam
