Cursory inspection of the code seems to suggest, for instance, that *transfomers* is not safe; the only references to this variable I see are in specials.lisp: (defvar *transformers* nil "Stack of currently active transformer objects.")

and in WITH-TRANFORMATION, which does not create a new binding for *transformers*, but rather just pushes a new transformation onto the global *transformers*.

The new release rebinds *TRANSFORMATIONS* and thus should hopefully fix this issue. Thanks for the report, Edi.
