First make sure that you use the slime-autodoc contrib. Then make sure
that the following is executed whenever you open one of your games'
source files:

  (modify-syntax-entry ?[ "(")
  (modify-syntax-entry ?] ")")

Now, we can customize the SWANK side. You can do that by using
~/.swank.lisp.

Basically all you have to do is to add an :AROUND method for the default
method of COMPUTE-ENRICHED-DECODED-ARGLIST like this:

  (defmethod compute-enriched-decoded-arglist :around
      (operator-form argument-forms)
    (unless (find-package "DTO")
      (return (call-next-method)))
    (let ((dto-method-arglist (dto:method-lambda-list operator-form)))
      (if dto-method-arglist
          (decode-arglist dto-method-arglist)
          (call-next-method))))

DTO:METHOD-LAMBDA-LIST should return the lambda-list of the method named
by the passed symbol.

I think that should be it. If you encounter problems, let me now.
