Testing this PR locally

If you don't have a local development environment setup, you can use Digger to test this PR:

dub run digger -- build "stable + dmd#14692"

ImportC should never have hijacked D syntax in the first place. We ought to define something separate.

@WalterBright : Release is not happening tomorrow, so can we have the conversation here about what the behavior should be?

I think things I've been pulled a bit fast, so we can either pull this fast as well (which is just adding to the confusion), or have a conversation, with the shared understanding that no release is going to happen without:
a) A solution that we agree on, OR;
b) This PR being pulled in the absence of a solution;

If you disagree with that approach, we can just pull this as-is.

[WalterBright]

@Geod24 thanks for the sensible approach. I'm ok with (a).

[WalterBright]

@adamdruppe the idea is so the user can change the language of the imported code without breaking the importer code.

[WalterBright]

Or more precisely, it shouldn't matter to the importer how the importee is implemented.

[ibuclaw]

Merging, because let's keep current broken behaviour in point release for now -> fix in next major.
