I remember using a langauge (Icon?) in which arbitrary bases up to 36 
could be used with numeric literals. IIRC, the literals had to begin 
with the base in decimnal, folowed by a "b" followed by the digits of 
the value using a through z for digits from ten to thirty-five. So

gunk = 36b8H6Z9A0X

would have been valid.
