You didn't ask me, but I'll pipe in anyway. Please don't. I consider "use English;" a huge mistake. Perl has enough magic variables that doubling the number you need to remember and the cognitive load associated to remembering them is just a huge pain in the butt. Consider, even if you "use English;" in your scripts you WILL encounter a lot of code that doesn't use them. So then you have to remember both. Since the "English" equivalents are fairly rare knowing what they are is mostly useless. Any time I have encountered "use English;" in code it is has wasted my time by requiring me to double check what "real" magic variable is being used. (For instance what is $OS_ERROR? is it $! or is it $? or is it $^E. Is it the same as $ERRNO? [rhetorical question]) If it were up to me we would deprecate and eliminate use English; At the very least we should warn people not to use it.
