enum are woefully underpowered in D, you cannot print them correctly,
cannot iterate over them,.. It's a pity because I think that it's a very
important structure (well less than array literals, but still important).

I was inspired by Robert to make also a templated enum version to print 
them, (and I'm probably not the only one) but it's a hack..

With macros, hopefully these hacks could become 'less ugly' enough that
we could integrate them in a library..
