RE: [Luna-scheme-discuss] contrib + any work going on w luna ?

[<bri...@co...>]

Glad to hear from you, Lars.  I fixed the apparent recursion bug (turned out to be a type-conversion Int32 to Double problem in the updated CLR).

I find Luna to be quite "real" enough for my purposes.  It's almost exactly what I had thought of doing in my own head actually (I had started to convert D. Betz's old XLISP, which I know very well, but had decided to start over from scratch when I Googled "R5RS C#" and Bingo !

I'll post as I progress.  My medium-term goal is to load assemblies dynamically and use reflection to build FFI's on-the-fly, somewhat as in http://www.angelfire.com/wa/brianbec/siodffi.html .  I am not sure what PLT is up to w.r.t. CLR, but I prefer the "hostile" style of FFI, just because it's less work on the old, tired fingers.  Having done it once for native code, it should pose no difficulties in CLR.

Ta ta, and thanks for the VERY fine work.  It's good to know that someone out there is still interested in the "Divinely revealed truth" of Scheme.
