          Issue ID: 18476
           Summary: -run should not only take the next argument
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

          Reporter: greensunny12 at gmail.com

echo "void main(){}" | dmd -run -c -

and fails with

---
Error: module -c is in file '-c.d' which cannot be read
import path[0] = /usr/include/dlang/dmd
---

I have seen people at my Meetup struggling with this and I was initially also
puzzled.
One really needs to know the implementation of mars.d to understand this.
