Just another example: I just learned that linking against C++ 
DLLs is quite limited. I ran into the issue that linking in an 
external variable doesn't work (even though the mangled name that 
D chooses is correct), because DLLs work differently than static 
linking does.
Someone with more in-depth knowledge told me, that Windows 
support in D and specifically DLL support is lacking quite a bit.

Having *only* link compatibility is totally fine, D currently 
just doesn't fulfill that promise, especially not on Windows and 
especially not with DLLs.
