To clarify on David's comment, js/console puts a literal 'console'
identifier into the generated js.
In your example, js/console is shadowed, because (defn console[] js/console)
is emitted as ns.console = (function console(){return console;});
The discussion to be had here is whether the (internal) name of the
generated js function should e.g. be mangled like let-binding:
ns.console = (function console_1337(){return console;});
Ticket?
