c(a|d)ⁿr

By Eutro
car, cdr, caaaaddddr, and everything in between.

(require cadnr) package: cadnr
c(a|d)ⁿr

This module extends a number of built-in Racket functions that have obvious arbitrary extensions.

C(a|d)ⁿr - car, cdr, caaaaddddr, and everything in between

Am I getting this right - this is happening at macro expansion - extending the racket compiler handle arbitrary combinations? Am I right in assuming it be approximately as fast as the native functions at run time? Stephen
