I’ve just published version 12.2.0 of Pulp. In addition to a smattering of bug fixes, this release includes source map support by nwolverson, and the ability to use Effect as well as Eff for your program’s entry point without having to explicitly tell Pulp that Effect is okay to use as an entry point via the --check-main-type option.
To upgrade, simply run npm install [-g] pulp.
