This is not valid. DMD and the grammar spec both do not allow
This was changed weeks ago. Now D accepts that code.
I don't support C-style declarations. DMD doesn't really
support them either.
Then I suggest DScanner to support the half-C-declarations,
because D compilers digests them just fine and they are very
common in D code you will find in the wild. A code analyzer has
to accept the real world code people write, otherwise it's much
less useful :-)
