It's not the problem mentioned but I had to struggle with DLLs

TypeInfo which does not pass DLL boundaries correctly so that
int != int in runtime even it's in fact a simple int.
If you need to exchange unknown data between a DLL and your
application you need to get a workaround and cannot use that
elsewhere settled nice feature. But it's a Windows specific
issue - it works as expected on other systems.
Which is basically same as in C++, despite the fact it does
have real working SO/DLL runtime's many large projects have
their own RTTI implementation. LLVM has its own RTTI because
standard type info is "inefficient", Unreal Engine has its own,
IIRC Qt too has its own, etc...
Same thing with D Variant, some people say it is
"inefficient"... so we ended up having multiple libraries.
Not saying anything about how good or bad all this, just the
facts.
C++ you need to write duplicate code (.h and .cpp)
C++ you need to care about header include order
C++ you need to forward declare everything you gonna use if it is
not included before
C++ you need to waste time waiting for compile
C++ you need to fight to get proper reflection
D is much more superior to C++ in my opinion, proper package
manager, great compile time, great module system, great interop
with C and C++
You can use GC, you can disable it, you can use malloc, it suits
all your need!
Can't find a lib? use a C or C++ one, that is what makes D so
much powerfull, you don't have to give up on other ecosystem, you
can embrace them in your project
