Throw an error for unknown a-z escape sequences as well as non-ASCII non-whitespace escape sequences.
Certain escape sequences express a unicode scalar and as such are valid in a range.
This is now done from the DSLTree.
As per PCRE, Oniguruma, and ICU, a first character of `]` is treated as literal.
Returning a constant pointer is extraneous and leads to a bunch of warnings. Since you don't control where the pointer is assigned you can't really control whether the pointer is const or not. The uint8_t inside can be const though.

Make sure we don't try and print things like empty comma lists `,,,,` or redundant parens for concatenations that had their trivia filtered out.
Turns out this is a Unicode-defined thing.
Previously we would just lex to the end of the input, as it was assumed only single-line regex would be supported. Update the implementation to handle multi-line, and take account of PCRE global options.
Start lexing `/.../`, and allow any number of pound signs to surround it.
When an extended delimiter `#/` is followed by a newline, enter a multi-line mode where the literal may span multiple lines, and extended syntax is enabled by default.
Leave only `/.../` (and its extended syntax) enabled for now.
Tweak the text to say that e.g `\I` is invalid.
