dissoc only turns the record into a map if you remove one of its core
fields:
user=> (defrecord Foo [x])
user.Foo
user=> (def f (map->Foo {:x 1 :y 2}))
#'user/f
user=> f
#user.Foo{:x 1, :y 2}
user=> (dissoc f :y)
#user.Foo{:x 1}
user=> (dissoc f :x)
{:y 2}
Keys that hold temporary objects, like server instances or connections,
should probably not be core fields.
