常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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.
