Here's the text: This looks like a tremendous improvement over the original Artistic License. I see nothing that conflicts with the DFSG in either spirit or detail. To whom can I address my questions and suggestions below? What is the license on the text of this license itself? The GNU GPL forbids modification of its terms even for application to works which aren't already covered by it (in other words, a claim of copyright over the text of the license itself). > 1.

One may not embed a modified version of the interpreter into a proprietary program? (I'm not saying one SHOULD be able to, I just want to be clear that I'm understanding this clause correctly.) It looks like section 8 may act as further clarification of this section, perhaps the two should be combined? > 6.

I am concerned that mentioning "undump" and "unexec" is a bit too technical for a license document. What you really want to cover is any method of aggregating the Standard Version with additional material, right? > 7.

I would suggest that "language" be promoted to a defined term; if I understand the intent of this section correctly, then it isn't just a programming language specification that you want to protect, but, for Artistically-Licenses libraries, the API or even ABI itself. If I misunderstand the intent of this section, and it is designed only to protect the specification of a programming lanuage per se, I would suggest that this section be made optional for authors who wish to license something other than a compiler or interpreter under the Clarified Artistic License, since it could be confusing and unnecessary. Regression tests are undefined and not likely to be a familiar topic to non-computer scientists reading the document. I would suggest either defining Regression Tests at the top of the license, or broadening the language a bit, or simply saying something like "provided these subroutines or variables do not function in any discernibly different manner when used in a manner that is syntactically correct with the Standard Version." This way people get to add to, but not subtract from, the defined interface. What is legal perl (for instance) remains legal perl. > 8.

Logically, I think this paragraph belongs with 5. -- G.
