#D

[Erik Naggum]

Scheme has #D for decimal. I have found this useful. a simple way to
obtain this in CMUCL follows, but I wonder whether it will find its way
into the language, and also why it isn't if it was decided against.

(in-package :common-lisp)

(defun sharp-D (stream sub-char numarg)
(ignore-numarg sub-char numarg)
(sharp-r stream sub-char 10))

(set-dispatch-macro-character #\# #\D #'sharp-d)

I don't think anyone ever proposed it for Common Lisp. There's already two
ways to enter decimal data: prefixing with #10R or appending a decimal
point. And since decimal is required to be the default radix, it's rarely
necessary to specify it explicitly (MacLisp defaulted to octal, so the
decimal point was used frequently).
