There are many languages that are close to D syntactically 
besides C++: Java, C#, Go, Php, even TypeScript…

Unfortunately, there are other bits missing atm that is a likely 
turn-off for C++-minded people (like a marketable memory 
management solution), but those are fortunately being worked on, 
or at least discussed with an open mindset.

I think many C++ programmers would want a higher level clean 
looking language with a comparable memory management story. D is 
fairly close, but the last mile is missing.
