lexer
A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.

It would be nice if subpatterns could be used within subpatterns.
#[derive(Logos, Copy, Clone, Debug)]
#[logos(subpattern a = r"[a-zA-Z!$%&*/:<=>?^_~]")]
#[logos(subpattern b = r"(?&a)|[0-9+\-.@]")]
pub enum Token {
#[error]
Error,
// ...
}Currently, this is not supported and causes a regex parse error.

Summary
The always-ff-non-blocking rule currently only flags basic assignments using the = operator. Blocking assignments using modifying assignment operators or unary increments and decrements evade an enforcement.
** Example **
Would it be possible to have the regex parser support character classes like \w within other character classes? I had a regex pattern earlier that used the character class [0-9a-zA-Z_\.-], and I attempted to simplify it with [\w\.\-]. I didn't notice this library doesn't support doing that, and was wondering just how difficult that would be to implement. For the time being i'm just expanding

Flex has a directive %option caseless to lex tokens in a case insensitive way.
Is there currently a way (besides using regular expressions) to accomplish the same?
