A site like cppinsights.io, but for D?

[Alexander Nicholi]

I just ran across this website <https://cppinsights.io/> that 
does some pretty interesting deconstructions of C++ code, and I 
was wondering if anything like this exists for D. Apparently the 
main purpose is source-to-source transformation to better show 
what the compiler sees in your code before it gets turned into IR 
or assembler or whatever.
