"The interpreter gateway has more options for exposing interp-level functions and types to app-level."
How does this work? We tried several builtin modules, as well as "select" module that you mentioned, all thses modules's interp-level code are invisble to other module's app-level. We would like to take your advices to make a new module. But the problem is how to make the new module's interp-level code visible to app-level?
