Reading with #\, as decimal point?
Does anyone on the list know if there is a standard idiom for reading where #\, is interpreted as the decimal point, e.g. such that I get CL-USER> (read-from-string "1,2") 1.2 3 CL-USER> Thanks in advance. -Klaus.

It doesn't get much simpler: (defun rfs (string) (read-from-string (substitute #\. #\, string))) > CL-USER> (read-from-string "1,2") > 1.2 > 3 Cl-USER 291 > (rfs "1,2") 1.2 3 Chhi'mèd
