I haven't looked at the rest of the code, but the first thing I saw is:

    (defmacro wsi-current-lexical-environment ()
      "Return the current lexical environment.
    
    If `lexical-binding' is not enabled, return nil.
    
    This macro expands to a Lisp form that evaluates to the current
    lexical environment. It works by creating a closure and then
    extracting and returning its lexical environment.
    
    This can be used to manually construct closures in that
    environment."
      `(let ((temp-closure (lambda () t)))
         (when (eq (car temp-closure) 'closure)
           (cadr temp-closure))))

which clearly assumes the code is interpreted since once compiled,
`temp-closure` is not going to be a list any more (and you won't be
able to extract the lexical env from it).
