Here's my semi-regular posting about erlang style numbers... this
time
as an excuse to play with Luiz' token filter. Below is the code to
support this interesting (to me at least) extension:
See, no need for C hacking! :-) And pretty easy to do it in Lua,
right?
(I'm not blowing my own horn here; just remarking that token
filters can be
a better alternative to hacking the Lua core to add more sugar.)
-- 2#1001 means base "2" numeric constant "1001" or 9 in decimal
Just note that you cannot enforce that the three parts are a single
token,
that is, 2 # 1001 will be accepted as a binary constant. Just
don't
tell your users about it :-)
