    Yup.  It is very common in Fortran, for example.

And Ada.

    How so?  We now bundle consecutive individual cases that go to the same
    case label in case ranges.  This is extremely common in non-GNU C, think
    about regular expressions for example.
    Dropping CASE_HIGH is a bad idea IMHO.

I agree.
