Some time ago on perl6-documentation (when it existed) we decided that
octals would now be represented as 0o777 and, in strings, \o777. Should
0777 and, in particular, \777 come with warnings? What, exactly, does
\777 mean in a string

J where you want to be explicit?
in a regex \d is a digit, so that isn't a good idea. it would be better
to require \0d. the others also need a base designator character so
decimals

In a rule, whitespace is a very good disambiguator.

I think nullbyte-d is rather likely to occur.
why would we need 0d123 as a literal?
Symmetry.
0x10

I think \777 should be chr(777). As should \0d777, should you want to

I don't think you can assume it'll only be confusing for a year. For
one

Well, we switched to square brackets for

Works for me. So when you really do want a \0 in the middle of a string
