Häufige Annahme

Passing duplicate words into Abbrev.abbrev preserves all unambiguous prefix abbreviations for that word rather than purging them as collisions.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• Passing duplicate words into Abbrev.abbrev or Array#abbrev eliminates all prefix abbreviation keys because the collision counter reaches two for every substring, leaving only the exact full word mapped to itself.
• Array#abbrev core extension is only defined after requiring abbrev.
• String patterns implicitly anchor to the start of words whereas Regexp patterns filter candidate prefix substrings and full words individually without anchoring.
• Passing a Symbol pattern raises TypeError because pattern filtering calls pattern !~ abbrev and Symbol#=~ does not accept a String.
• Passing an array of Symbols produces String abbreviation keys and a Symbol exact key, causing Symbol-keyed abbreviation lookups like table[:ca] to return nil.
• Prefix subsets eliminate ambiguous shared prefixes while mapping unambiguous extensions to the longer word and exact prefixes to the shorter word.
• Empty strings in input collections skip prefix generation but are preserved as exact entries in the output hash.
