Are you sure you aren't just used to the x in 0xff? I.e., if the leading
0 were just an alias for 16, we could use 8x664 instead of 8r664.

BTW Ada uses radix prefix, but with # separating the prefix, so we can't use that.
How about apostrophe as separator?

     8'664   # or the suffix version could work also, although you'd have to back out of some names:
       664'8
       bee'16
