Installed with sudo apt-get install gdc in Ubuntu 18.04 - Can't compile a simple program.

[Stefanos Baziotis via D.gnu]

Hello everyone,

I just installed GDC with sudo apt-get install gdc and I can't 
compile a simple hello world program. I get e.g. static foreach 
errors:

/usr/local/include/d/core/internal/hash.d:333:16: error: basic 
type expected, not foreach
         static foreach (i; 0 .. T.sizeof / size_t.sizeof)

Any idea? Before about a month I used to compile hundeds of lines 
but I don't remember how..

Thanks,
Stefanos
