I've found it pretty annoying that we can't host examples on sites such as Stackblitz. The only workaround to this is to compile the compiler to a WASI module.

Initial experiments are promising. Compiling to target WASM works without much trouble thanks to the dotnet-wasi-sdk. To get it fully working a few changes need to be made:

• Logging has to be majorly refactored as Spectre.Console makes calls to System.Console which raises System.PlatformNotSupportedException exceptions.
• Disk access is tricky. WASI supports a virtual file system, so I'll need to play around with that; otherwise we'll need to have a WASM specific strategy for finding/parsing the config and spitting out generated code
• We don't rely heavily on reflection, however, I think this is still a great opportunity to refactor flag parsing.

I'll track progress here. I think this is worth having for 3.0 for the sake of making example apps easier to share.

Logging works now (50db574), thank you @patriksvensson for putting me on the right track.

All that is left to do is the WASI wrapper for the .wasm build to orchestrate the runtime. That, and write a polling file system watcher for when we’re running under WASM. I’d like the compiler to be 1:1 with native.
