Optimization

Here are some possible optimization techniques we can apply to code sections if they turn out to be slow. Be sure not to prematurely optimize: if you get that itch, put it here!

• Make Tokens Flyweights (may prove problematic, probably not worth it)
• Rewrite regexps into PHP code
• Serialize the Definition object
• Batch regexp validation (do as many per function call as possible)
• Parallelize strategies
