Any thoughts on support WASM extensions? #4

Are there any thoughts on how to handle WASM extensions?
If an extension is implemented should it be always on or behind some sort of "feature flag" mechanism?

I'd love to support some of the extensions, though I don't think I'll have the time to work on any soon. I think in cases where an extension might change the behaviour or perf characteristics of compiled WASM, we'll have to make the extensions opt-in. But, I haven't been following closely enough so I don't know if there even are extensions like that. For example, I think the tail call extension just adds new call and return instructions to support tail calls.

Thanks for the reply. I have been thinking about hacking on the vm a little and wanted to make sure I didn't do anything you may hate 😄
