Global filehandles and two-argument open are additional red flags.

True, unless one is writing scripts that must run on older systems which came with perl 5.005_03 and can't be upgraded in a timely manner. There's still a lot of Solaris 8 out in the wild to which this applies.

    You can use Symbol::gensym on such old perls to get lexical filehandles (more awkward, but gets you the same benefits), and you could write a conditionally installed wrapper to emulate three-arg open (only awkward once, but only worthwhile when you can foresee value in making the code easily forward-upgradable). Whether the effort is justified will depend on your particular circumstances, of course (but see also my signature).

    Makeshifts last the longest.
