- "Given a pattern and an environment, try to find a class or trait using several strategies:
- - EXACT: If there is a class or trait whose name exactly given by pattern, return it.
- - UPPER: If the pattern is upper-case only, find camel-case letters with that sequence.
- - WILD: Try the pattern as-is for regular wild-card search.
- - FEATURE: Split patterns at feature boundaries and insert wild cards between.
- - FUZZY: Split patterns at feature boundaries BUT treat each feature as a full class name.
- If there is only one class or trait in the given environment whose name matches pattern, return it. Otherwise, put up a menu offering the names of all classes that match pattern, and return the class chosen, else nil if nothing chosen.
