Implementation Notes

We are generating some helper classes on types by using http://clipperhouse.github.io/gen/. Do the following to regenerate these if necessary:

go get github.com/mjibson/esc
go get github.com/clipperhouse/gen
go get github.com/clipperhouse/set
export PATH=$PATH:$GOPATH/bin  # If you haven't already
go generate

Generated Stdlib

To regenerate the standard library, do:

./reset_stdast_go.sh && go run cmd/dumpstdlibast.go
