assert Abbrev.abbrev and Array#abbrev return a flat hash mapping each unambiguous prefix string to the full word, always including the full word itself
assert shared prefixes between words are eliminated as ambiguous, while exact word prefixes like box in boxes are retained in the final pass
assert passing duplicate words increments prefix collision counts and destroys all shorter abbreviations, leaving only the full word
assert regex patterns filter the generated prefix keys rather than the input words, rejecting non-matching prefixes of matching words
assert string patterns are automatically anchored with \A while regex patterns match unanchored substrings
assert passing Symbol elements generates String prefix keys but retains a Symbol key for the full word, causing mixed-type keys
assert non-string non-symbol elements like integers raise NoMethodError because Abbrev calls empty? without coercion
assert require 'abbrev' monkeypatches only Array#abbrev, while Enumerable#abbrev and Set#abbrev remain undefined
