Automated source translation of C++ to D

[Joakim via Digitalmars-d]

C++ support keeps coming up these days, with Andrei continually 
stressing it as something to work on.  How hard would it to be to 
write a C++->D translator, to allow people to translate C++ 
libraries to D?

I've been using tools like DStep and looking at libdparse, which 
seem to work very well.  I just translated a C sample app from 
the Android NDK to D, fairly simple stuff like turning -> into ., 
adding a default in a switch statement, rewriting casts from 
C-style to D-style casts, removing the struct label, nothing that 
couldn't be automated.

I'm sure there's stuff that'd need to be done by hand, but if you 
can automate 97%, that's good enough.  Could this be a viable 
option for many cases?
