FWIW here is that list of features that are different between Python and my

This is not an attempt to compare the complete languages as they are for
different purposes (mine is more low-level, simpler, smaller and designed to
make it easier to create an efficient byte-code interpreter for it).
"I think Python now has hex, octal and binary literals. X allows any
base from 2 to 16: 2x10101 is binary, while 4x101 is quaternary (ie.
20)."
Do you mean that 4x101 means 1*(4*4) + 0*(4) + 1? If so, it would be
17, not 20. Is this a typo in the document, or am I misunderstanding
your syntax?
Just a mistake. The example had been 4x100 which is 16, but I changed it
to 4x101 for a bit less confusion, which as you say is 17 not 20 which
is 4x110.
(Although not used much, I have used quaternary here for example:
4x3032_3233_2323
The digits represent the number of extra days more than 28 in each
month, from Jan to Dec.)
Smalltalk uses "r" (for "radix") rather than "x", and can handle any
base from 2 to 36.
