Perform common operations on lists, such as sorting, finding unique items, and counting distinct entries.
Quick line-by-line operations on a list of items — sorting, deduplicating, reversing, shuffling, and counting occurrences — for cases where firing up a script or spreadsheet is overkill.
Deduplication is case-sensitive and exact-match, so "Apple" and "apple" are treated as different items unless they match exactly.
Each distinct item followed by how many times it appeared, sorted by frequency (most common first) — useful for quickly spotting duplicates in a pasted list.
