Summary of Problem

I found different behaviour between the main branch version and the 1.26.0 release. I am not really sure, which of them is correct, but it seems like the main version is a bit confusing.

Steps to Reproduce

hello2-module.chpl:

module B {
  proc b() {
  } 
}
module A {
  proc main() {
    public use B;
    B.b();
  }
}

chapel 1.26.0 compiles it and works fine

main version has a compilation error:

hello2-module.chpl:6: In function 'main':
hello2-module.chpl:8: error: 'B' undeclared (first use this function)

Also, imports and private use work fine in both cases.

Compile command:
chpl hello2-module.chpl

Execution command:
./hello2-module
