NOT11 — Use of lexical components

  • Key: NOT11-14
  • Legacy Issue Number: 1680
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Firstly, due to the use of lexical components such as "and", "or",
    "not", etc., the grammar is not context free. A backslash (I assume the
    syntactic category <CompEsc> is a backslash) is used to distinguish
    runtime variables from symbol names, and this is enough to ensure that
    any symbol subsequent to "\" is treated as an <Ident>.

    However, the <CompDot> lexical category doesn"t provide for an escaped
    <Ident>. However, I believe the following is legal IDL:

    struct A

    { long and; }

    ;

    This leads to a situation where a constraint such as:

    $.A.and == 34

    must be regarded as syntactically incorrect for the grammar to remain
    context free.

    I believe that the issue can be resolved without ambiguity by extending
    <CompDot> to allow a backslash followed by a <CompIdent>.
