Well, they can argue with the client's security officer. I did specify it
as a preference rather than a total inability. It's all very well

two ways of doing something, I'm going to pick the one that involves the
least interaction, especially with a scarce resource who's doing something
more important for me.

Not if they're reading the reference in "Perl in a Nutshell", which gives
no real indication of depth traversal. If they started with perldoc, they

Not for the sake of golfing, but for clarity and simplicity. I don't
believe in recreating OS functions in user-space if it can be avoided. (I
see this happening a lot in modern programs, perhaps because programmers
feel a compulsion to use the stuff they were forced to learn in CS.)

I'm only going to worry about performance if it turns out to be noticeably
egregious in practice. "Premature optimisation.. &c".
