There is no need for the arguments usage in the defrecord constructor and it's a perf hit for construction. We should always construct defrecords by passing in the extra three arguments: __extmap, __meta, and hash automatically.

Comment by Peter Schuck [ 16/Dec/14 11:59 AM ]

The constructor now has __extmap, __meta, and __hash in all the places it's constructor is called, the positional factory, map factory, and direct constructor invocation. This is the first time going deep into the ClojureScript compiler so there may be some clean up to do or other places a records constructor is called that I didn't take care of.
