npmccallum commented on issue #4947:

@pchickey I disagree strongly that downcasting should ever be used in wasi-common. In our wasi implementation, we are regularly working around downcasting just to make things work. Adopting downcasting in the first place was a huge mistake.

@npmccallum OK, send a PR to fix it then

npmccallum commented on issue #4947:

@pchickey I discussed this and other issues with @sunfishcode and he recommended that I not try to patch the existing implementation and wait until preview2. Should I file an issue requesting the removal of downcasting under preview2?
