If write_file() atomic gets an error renaming its temp file to the
intended destination then that temp file is left behind. I'd be good to
remove it.
For example, create a file /tmp/other owned by root, then as ordinary
user
use File::Slurp;
write_file('/tmp/other', {atomic => 1}, "hello");
=>
leaves its /tmp/tempXXXXXX
A sticky-bit directory like /tmp should be the most common case where
you can get as far as creating the temp but then can't rename to the
target.
