Some options :)
Erlang isn't in the list, but it looks to me pretty similar to Ada in
the numeric syntax. I suspect that syntaxes are like people's names:
they go in and out of fashion.

And I really don't want to write things like this anymore:

If you do write a patch for this, may I suggest the following syntax,
borrowed from Erlang (which possibly borrowed it from somewhere else):
local opcode = op == "movzx" and 16#0fb7 or 16#0fbf
simply because it is far more general and orthogonal - if you want
constants you can prefix them with 8#, and binary constants with 2#.
There's no need to remember arbitrary conventions for which prefix goes
with which base, and (FWIW!) you can recognize odd bases like 3# or 9#
just as easily.
(Note that I'm not suggesting # as an infix operator - it's a purely
lexical delimiter... a lot like a decimal point, actually.)
