Caching for Repeated Parsing

I'm working on a performance-critical project that requires repeated parsing with parseclj. I'm interested in knowing whether there's built-in support for caching parsed results. If not, would memoization be an effective way to add this feature? Additionally, are there any caveats or issues to be aware of when implementing caching in conjunction with parseclj? If there's any places I should look, let me know.

Thanks!
