A few comments from a outside developer who puts things in PLaneT.<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
First questions regard performance. First, is there an inlining directive (or delcaration or proclamation, etc.)<br>
Second, are there type proclamations to speed up common fixnum arithmatec, vector indexes, etc. Is there<br>
are role for typed-scheme here?<br>
<br></blockquote><div><br>Several other have noted the new 'unsafe' operations that have been added. I have update the science collection to make use of these. Actually, I find them more of a help with floating point operations than with fixed. [Most cases where I use exact integers, there is no guarantee that there are indeed only small integers (fixnums) as opposed to large integer (bignums) or any good reason to make such a restriction, but there are exceptions - string and vector indices, etc.] I haven't released these to PLaneT yet because I haven't done enough testing and I am using some that aren't in the released 4.2.2 (e.g., unsafe-fx->unsafe-fl and unsafe-flabs).<br>

Fourth, Is there a formal roadmap for the Planet libraries - a sort of wishlist from the core development group<br>
or user community vote/consensus. Similarly, is there an up to date raodmap for the core PLT system?<br>
<br></blockquote><div><br>Maybe it is time for a PLT Scheme Users group or something similar. I would love input on my own packages, etc.<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

To boil all this down to a general scheme community question, PLT has become *very* popular in the<br>
scheme community (programmer community, to a lesser degree) at large. How stable a platform does<br>
it present for a future canonical open source project should the academic group behind PLT abandon<br>
the platform for one reason or another (lack of funding, changing research focus, etc.)<br>
<br></blockquote><div><br>Several of us non-academics (although I am an ex-academic) have enough faith in the core group and the product use PLT Scheme in our work.<br><br></div></div>Doug<br>
