And you have to remember to set it back at the end. Why not let perl remember 
for you?

{
    local $/ = "whatIwant";

    dostuffwithappropriatecalls();
}  # everything is back as before

If you want to localise a value, don't use a ``global'' assignment and make 
the maintenance programmer search for the other half of your intention: use 
the facility the language provides, and put the information in one place.

my localises a name in space; local localises a value in time. There are two 
keywords because these are two different things.
