I did a little interpreter where non-base 10 numbers
(up to base 36) were:

     .7.100   == 64  (octal)
     .9.100   == 100 (decimal)
     .F.100   == 256 (hexadecimal)
     .1.100   == 4   (binary)
     .3.100   == 9   (trinary)
     .Z.100   == 46656 (base 36)
Advantages:
Tokenizer can recognize chunks easily.
Not visually too confusing,
No issue of what base the base indicator is expressed in.
