PCRE treats them as octal, but we require a `0` prefix.
Ban multi-scalar characters that start with ASCII, and are not letters, numbers, or `\r\n`. These may be confused with metacharacters and as such should be spelled explicitly.
Ban a balanced set of `<{...}>` delimiters for a
potential future interpolation syntax.
