Good idea, thanks. I had a look at the implementation of it, and at the way
it is integrated into the go toolchain. Unfortunately, it doesn't seem
possible to include extra compilation stages in the toolchain. I was hoping
for a way to insert an extra step to be able to modify the AST to insert
tracepoints.

So, for example, coverage is built inside `go test` by directly calling `go
cover`, and it doesn't use any plugin interface :(
