Multiple namespace loading behavior

Addendum: There is additional error checking in require that checks whether the namespace with the require'd name was created when require is nearly done, but it is only enabled if you use the :as clause. Example given the contents of test_ns.clj above:

user=> (require '[test_ns :as myalias])
Loading...
Syntax error compiling at (REPL:1:1).
namespace 'test_ns' not found after loading '/test_ns'

That additional error checking is also enabled by doing (use 'test_ns)
