[issue10093] Warn when files are not explicitly closed

[Marc-Andre Lemburg]

Marc-Andre Lemburg <mal at egenix.com> added the comment:

I wonder why you think a warning is needed if files aren't closed explicitly. The fact that they get closed on garbage collection is one of the nice features of Python and has made programming easy for years. 

Explicitly having to close files may have some benefits w/r to resource management, but in most cases is not needed. I disagree that we should discourage not explicitly closing files. After all, this is Python, not C.
