Both Cray CCE `ftn` and Intel's `ifx` throw multiple errors with the Flang example (test) code in this pull request. 

Intel's `ifx` will warn, but not error, with the Cray example code.

A current master branch `flang` will warn, but not error, with the Cray CCE example.

So I would object to this new implementation's syntax being incompatible with the existing Fortran compilers.

Is there a compelling reason for Flang to be different from the major vendors? This is especially concerning when there are existing codes in the wild which will break or see significantly degraded performance if they use `flang`.
