Warning: jptxs has recently completed Programming Perl and the knowledge is still settling : )

From a performance standpoint, is there any reason at all to pass anything but a reference into a subroutine? I mean, if you just end up clogging up more memory with the copied scaler/array (I take it for granted at this point hashes should be passed around as refs), can there be a situation where it would be better to pass an actual variable than a reference?

I'm sorry if this question is too broad - if so, just let me know. Just trying to get it all right as I can : )

-- I'm a solipsist, and so is everyone else. (think about it)
