Bug Report

Performance issue: KCL evaluates unused package fields.

1. Minimal reproduce step (Required)

Run script:

#!/bin/sh

mkdir -p unused_pkg

cat > kcl.mod <<EOF
[package]
name = "__main__"
edition = "0.0.1"
version = "0.0.1"
EOF

cat > main.k  <<EOF
import unused_pkg
EOF

cat > unused_pkg/data.k <<EOF
show = lambda s -> str {
    print(s)
    s
}

foo = {
    name: "foo"
    value: show("foo")
}
EOF

kcl run .

This script creates files:

• kcl.mod

  [package]
  name = "__main__"
  edition = "0.0.1"
  version = "0.0.1"
  

• main.k

  import unused_pkg
  

• unused_pkg/data.k

  show = lambda s -> str {
      print(s)
      s
  }
  
  foo = {
      name: "foo"
      value: show("foo")
  }
  

And run main.k.

2. What did you expect to see? (Required)

I expect that top-level unused variables is lazy evaluated.

{}

3. What did you see instead (Required)

I see labmda output on unused top-level variable evaluation.

foo
{}

4. What is your KCL components version? (Required)

0.10.9-linux-amd64
