If I decided to develop my own custom micro-controller as well, only
mine uses base [put random number here] or what ever other valid reason
I have for working with numbers in some base, should I ask for that base
to be added to the language as well?
A more general solution is to allow arbitrary base representations. don
suggested toBase!(base)(number) or something similar. adding syntax
sugar for that is better IMO than just adding base 4.
here's a first attempt:
<number>B<base>. so 01010101B2 is a binary number. compiler will check
that the digits are in the proper range, so 123B2 is a compile-time
error.To represent the digits we can use English letters as in Hex or
have another syntax form like 123#112#323#334B1000
