dot form silently drops additional (invalid) args

Question

If the second argument to {{.}} is a {{seq?}} every additional arg is silently dropped. In CLJS this throws a compile error.


(. "xyz" (substring 1) (throw :bug?))
=> "yz"


Might be neat to at least get a warning since it's not immediately obvious when accidentally using {{.}} instead of {{..}}.
