The error is not from defmacro* but from the code you generated using defmacro*.

A misunderstanding.  Think harder about what your macro does.  E.g. try
(macroexpand '(test1 :lang 'toto)) and (macroexpand '(test1)).
During macroexpansion, your `lang' is not supposed to hold a "language
value" but "a Lisp expression that will evaluate to a language value".
