No, it's not that gray: in 1.2 (so in clojure master, and all new branches like prim, equal, etc.), ^ now has the same semantics as #^. #^ is still working as usual, but becomes deprecated. The behaviour of the old ^, as mentioned by Howard, requires the explicit (meta ) call. Howard, another point to have in mind in 1.2: some libraries from clojure contrib have partially migrated to clojure. For example I/O stuff has appeared in clojure.java.io. String manipulation stuff also. As a result, you may encounter warnings in your own code, or in libraries you use which may not yet have migrated to 1.2 (which is to be expected, since 1.2 is not out), or not be prepared for 1.2 (by avoiding 'use-ing foreign namespaces, but rather using aliases). The warnings will tell you when a var is re-def-ined (this is a new feature, which may or may no stay in core : before this warning feature, you just wouldn't have been able to compile the code, redefinitions of vars bound to external namespaces vars was an error. The new "warning only" behaviour tries to enhance the user experience: allow the code to run, until everybody has removed the warnings in new versions of their code).
