lexical scope
     
         or "static scope" in a lexically scoped
        language, the scope of an identifier is fixed at compile
        time to some region in the source code containing the
        identifier's declaration.  this means that an identifier is
        only accessible within that region including procedures
        declared within it.
     
        this contrasts with dynamic scope where the scope depends on
        the nesting of procedure and function calls at run time.
     
        statically scoped languages differ as to whether the scope is
        limited to the smallest block including begin/end blocks
        containing the identifier's declaration e.g. c, perl or
        to whole function and procedure bodies e.g. ?, or some
        larger unit of code e.g. ?.  the former is known as static
        nested scope.
