neat! Given the low footprint of WASM apps maybe this could maybe 
be used to have small isolated, cross-platform DMD tools that run 
one-shot? Could for example run the WASM binaries from the IDE 
and because it's WASM running in the own process, with memory 
that we can free, it avoids low startup times, especially on 
windows.

Do we have some WASM runner in D?
