bindgen 0.5.0 fails to handle (transitive?) versioned imports #281
Description
It appears that the 0.5.0 version of the bindgen has introduced a regression
go run go.bytecodealliance.org/cmd/wit-bindgen-go generate -vv -w imports -o bindings wit
fails on e.g. wasi:http, examples:
- https://github.com/rvolosatovs/go-bindgen-repro
- (manual) execute these steps:
$ git clone https://github.com/WebAssembly/wasi-http
$ cd wasi-http
$ go mod init repro
$ go get go.bytecodealliance.org/cmd/wit-bindgen-go@v0.5.0
$ go run go.bytecodealliance.org/cmd/wit-bindgen-go@v0.5.0 generate -vv -w imports -o bindings wit
