meme-lang.lexlets — io.github.xpojure-lang/meme-clj 3.0.0

Meme lexical scanlets: character predicates, consume helpers, and trivia consumers.

This file provides the lexical layer for the meme language. The grammar spec in meme-grammar references these functions by name. Generic scanlet builders (atom-scanlet, single-char-scanlet, delimited-scanlet) live in meme.tools.lexer.
