[plt-scheme] Questions on PLT status and project structure

A few comments from a outside developer who puts things in PLaneT.

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).

Maybe it is time for a PLT Scheme Users group or something similar. I would
love input on my own packages, etc.

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.
