Identify the version and variant of any UUID. Supports versions 1-8, Nil, and Max UUIDs with detailed information.

Validate UUIDs (Universally Unique Identifiers) and parse their components. Check if a string is a valid UUID format and extract version and variant information.

Validate ULIDs (Universally Unique Lexicographically Sortable Identifiers) and parse their components. Check if a string is a valid ULID format and extract timestamp and randomness parts.

Generate all possible expansions from brace patterns. Expand bash-style brace patterns like '{1..5}', '{a,b,c}', or file-'{001..100}' into complete lists.
