    66'''Remove support for 'define' keyword.'''  (milestone:panc-8.0.0) This keyword actually serves no real purpose in the pan language.  Support for this keyword requires larger look-aheads in the lexer/parser and slows down the parsing with no benefit.
    77
     8'''Remove support for 'declaration' and 'descro' keywords.'''  (milestone:panc-8.0.0) These keywords perform no useful purpose in the current implementation of the compiler.  The information they convey can be equally well represented with comments.  These keywords will be removed.  Eventually a more general annotation facility will be added to the language.
     9
    810'''Remove delete statement.''' (milestone:panc-8.0.0)  The functionality this statement provides is also provided by an assignment to 'null'.  The assignment is more in keeping with a declarative language.  Moreover, the conflict between this keyword and an identically named function complicates the pan grammar.
