State of D for webassembly

[Chris Piker via Digitalmars-d-learn]

Hi D

Our group has some spectragram (aka dynamic spectra) creation 
algorithms that are fast in Java and since D has many Java-ish 
concepts it looks like it would be do-able to port the code to D. 
If I take on this project my target would be to run as a 
webassembly program.

What is the general state of support for GC dependent D-code 
running as webassembly?  If the runtime is not ready that's okay, 
just wanted to inquire about the state of things.

Thanks,
