Hi,
it seems that Fedora will provide D out of the box in their distribution.
But they seem to be providing an old version of it.

D2 doesn't have an open source compiler, so it can't be included in the
main repositories for Fedora.

In C# you are able to create and compile programs at runtime.
And if you take a look at the Google C++ style guide you see that for a
