-- This package defines type Dictionary derived from Table. It has same
-- functionality as the base type, but intended for keeping only valid
-- case-insensitive names. The case is ignored when matched (Find,
-- Get), but kept by the table. Additionally, any non-empty chain of
-- characters from the set Blanks is considered equivalent when
-- matched. The procedure Check_Spelling is used to check spelling of a
-- name before placing it into the table. It may raise Constraint_Error
-- to indicate a wrong spelling. The procedure Check_Matched is used to
-- check whether the matched keyword is a proper name. It is called
-- from Get with Pointer set to the first character following the
-- matched name. It returns True if the name fits. Usually an
-- implementation checks whether Source (Pointer) is neither a letter
-- nor a digit. Check_Matched is never called with Pointer outside
-- Source'Range.
