Recently, the attach feature poses two problems.
- It says that "attach" is deprecated and that we should use "%attach". Why?
- The real problem: "attach" and "%attach" now create a huge amount of stupid files in the folder. Why? How to prevent this?
- How could the Sage developers let such an annoying thing make it in a Sage release and, worse, not correct it in newer versions?
Thanks in advance!
