[plt-scheme] Application of PLT-Scheme

This is neat!

Questions:

1. Did you implement AutoLisp via an interpreter or via a macro  
translator from AutoLisp to PLT Scheme? We employed the latter  
strategy for both Dracula and Typed Scheme and like it a lot. (I know  
AutoLisp is dynamically scoped, so this latter would be challenging  
for the border cases.)

2. Did you implement a language level in DrScheme for AutoLisp?

3. Did you need to interface with the AutoCAD graphics engine at all?

4. Do you use MysterX (COM) to connect to Excel?

5. Did you consider writing a translator from AutoLisp to PLT Scheme  
so that your AutoLisp developers could read the target code and  
develop in Scheme directly?

Background: The AutoCAD people briefly considered PLT Scheme as a  
replacement for AutoLisp in the late 90s. At the time, they claimed  
that AutoLisp is the most widely used Lisp dialect with some  
100,000,000 lines of code in circulation (kind of like Emacs Lisp).  
But they realized that dynamic scope was extremely taxing and became  
incomprehensible, especially because companies wishes to sell these  
components and glue them together. They ended up moving into VB and  
asked a small company from Penn to develop a lexically scope  
alternative to the original AutoLisp. I don't know what happened.
