My version of semgrep-go is 7d35e5cd. Go version is go1.16 linux/amd64.

Yeah, I think you need to go get the .../dsl package explicitly.

I finally got the time to check, and yes, you have to go get the package with:

env GO111MODULE=off go get github.com/quasilyte/go-ruleguard/dsl

@quasilyte, I think you should update your README, because since Go 1.16 the default behaviour for go get is to use Go modules, so you need an explicit GO111MODULE=off to actually put the package into $GOPATH/src.
