Disallow variable shadowing

    XMLWordPrintable

    Details

      Description

      Extend the scope of variable declaration to the whole function (this puts CTL to sync with Java and allows seamless compilation of CTL to Java).

      https://en.wikipedia.org/wiki/Variable_shadowing

      Example:

      function integer transform() {
    integer b=10;
    for (integer c=10; c<100; c++) {
        integer b=20;
    }
}

      Should lead to something like: Error: Line 4 column 5 - Line 12 column 16: Duplicate variable 'b’!
