In order to maximize a number of targets of this lexer, let's decide some designs: * We don't distinguish `Terminal Symbol`. * We do assume that `NonTerminal Symbol` are always enclosed with arrow brackets. * We do assume that `NonTerminal Symbol` may include any printable characters except arrow brackets and ASCII 0x20. This assumption is for `RBNF `_. * We do assume that target notation doesn't support comment. * We don't distinguish any operators and punctuation except `::=`. Though these decision making might cause too minimal highlighting and you might be disappointed, but it is reasonable for us.

Various implementations of PEG have made different decisions regarding the syntax, so let's try to be accommodating: * `<-`, `←`, `:`, and `=` are all accepted as rule operators. * Both `|` and `/` are choice operators. * `^`, `↑`, and `~` are cut operators. * A single `a-z` character immediately before a string, or multiple `a-z` characters following a string, are part of the string (e.g., `r"..."` or `"..."ilmsuxa`).
