A few weeks ago, some optimizations to PARSE-TYPE and FOREIGN-ALLOC (which was calling PARSE-TYPE more often than necessary). What's your use case?

Ugh. That should read "some optimizations ... were made".

Every invocation of FOREIGN-STRING-ALLOC eventually invokes PARSE-TYPE, and we use it a lot.

Thanks to the optimization mentioned above (a compiler macro for foreign-alloc), foreign-string-alloc calls PARSE-TYPE only at compile-time.

My guess is that the PARSE-TYPE calls you're seeing are coming from FOREIGN-ENUM-{VALUE,KEYWORD}, which is one of the few places where calls to PARSE-TYPE at runtime haven't been optimized away into compile-time, yet. Can you confirm this?
