Some v-mode regexes are marked invalid when actually valid, such as a character class subtracted from a bare Unicode property character class.

Lint Name

no-invalid-regexp

Code Snippet

// Lint error "Invalid RegExp literal: Rework regular expression to be a valid deno-lint(no-invalid-regexp)"
const re = /[\p{N}--0]/gv;
// works fine at runtime, logging ['1', '2', '3'] as expected
console.log('1203'.match(re));
// identical semantics and runtime behavior, redundant brackets around unicode property eliminate the lint error
const re2 = /[[\p{N}]--0]/gv;

Expected Result

No lint error for regexes like /[\p{N}--0]/gv

Actual Result

Lint error
