Why Scheme?
First of all, it's a Lisp.
Universal (implemented for many platforms, many times.)
Venerable (around for a long time, still going strong. Roots in deep places.)
Simple. (Language and implementation.)
Well documented. (SICP, 'nuff said. But etc. & et. al.)
Unconventional but uncontroversial.
Compile and REPL.
(Optional strong typing.)
Because it's old and well-used it has everything ("Batteries Included" or easily available.)
Compact and elegant code.
Ooo! And it makes a nice target for compiling Joy expressions!
The Numeric Tower!
I think I've settled on #Scheme the host language for my Xerblin project. Reasons: It's a Lisp; implemented for many platforms, many times; venerable (around for a long time, still going strong, roots in deep places); simple (language and implementation); Well documented. (SICP, 'nuff said); lots of compilers; libs for everything; compact and elegant code;it makes a nice target for compiling Joy expressions; The Numeric Tower!
