+ -- Expect. Returns True for an exact match or a probably misspelling, False
+ -- if no near match is detected. This routine is case sensitive, so the
+ -- caller should fold both strings to get a case insensitive match.

+ -- Note: the spec of this routine is deliberately rather vague. It is used
+ -- by GNAT itself to detect misspelled keywords and identifiers, and is
+ -- heuristically adjusted to be appropriate to this usage. It will work
+ -- well in any similar case of named entities.
