          Issue ID: 13239
           Summary: Code is generated for unused lazy expressions
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: bugzilla@digitalmars.com

Given the code:

---
void log(A...)(lazy A args) { }

int fun(string[] args) {
  log("hello " ~ args[0]);
  return 43;
}
---

Code is generated for ("hello " ~ args[0]) even though it is unused. This can cause significant unwanted code bloat.
