[Python-Dev] Remove tempfile.mktemp()
-1. Please don't remove tempfile.mktemp(). mktemp() is useful to
create a temporary *name*. All other tempfile functions create an
actual file and impose additional burden, for example by making the
file unaccessible by other processes. But sometimes all I want is a
temporary name that an *other* program will create / act on, not Python.
It's a very common use case when writing scripts.
The only reasonable workaround I can think of is to first create a
temporary directory using mkdtemp(), then use a well-known name inside
that directory. But that has the same security implications AFAICT,
since another process can come and create the file / symlink first.
