'use strict' has nothing to do with passing stuff to subs. It is
a compile-time pragma that catches common errors due to misspelled
variable names, use of symbolic refs, etc.
When you add 'use strict' to an existing script, you need to declare
the variables used, typically by using 'my' (but sometimes by 'use vars'
or 'our').
So, if you use an array @headers in your script, you simply need to add the
line
my @headers;
to the top of your script. Likewise with other variables like this.
That's all you need to do.
Now, if you misspell it somewhere in your script as @heders, or use
$headers{0} when you meant $headers[0], you'll get a nice compile-time
error message instead of having to track down why your program isn't
behaving properly.
