matchertext

Matchertext is a syntactic discipline that allows strings in one compliant language to be embedded verbatim without escaping (e.g., via cut-and-paste) into itself or another compliant language.

Matchertext defines a syntactic invariant requiring that all bracket-like characters (parentheses, brackets, braces) are balanced within any well-formed string in a compliant language. This property enables verbatim, zero-escaping embedding of matchertext-compliant strings across language boundaries, eliminating injection vulnerabilities and parser ambiguity that arise from ad-hoc escaping conventions.
