The recommended usage of open is:

The three argument is preferred as a malicious user could enter a
file name that starts with '>'
It is preferred in code that accepts file names as user input and
doesn't perform taint checking. If the program uses a hard-coded
filenames, then no hurt, no foul. There can be no malicious user until
there is first a user.
There's no time like the present to learn good habits.
When someone is trying very hard to learn to write Perl that works at
all, I think it is /not/ the time to regale him with the rigours of
professional programming.
