Re: (jeffa) 3Re: Arrays

I get (no pun intended) how the original get_array works. What I'm unclear on is why you called it with &get_array() instead of just get_array(). I'm used to seeing \& used when setting up references to subs, but this is the first time I've encountered &subname() without the backslash.

Oh! /smack forehead :P I only did that because that's how Jaspersan called the function. Personally, i hate prefixing function calls with the ampersand unless i am taking a reference to them, as you can probably tell from the rest of the code i posted. However, tye has chastised me for this, and i understand why - because it distinguishes your functions from Perl's internal functions.
