Will existing lisp infrastructure be useful with TwinLisp?
TwinLisp has been developed so that any existing lisp code and/or skills are 100% relevant. You may start to use TL alongside with CL, even mixing the two in the same file. Developer’s with C/Java/Python background can now quickly start writting code for lisp machine, while getting used to things like macros, etc. Lisp developers may use either TL or CL — there is no technical difference.
