JD> Any reason to use named variables than to use the default variable ($_) ?
yes, you can read the code and see what the variable is for. $_ is
useful in some situations but not for foreach loops and similar
things. names are important in code and $_ has no name. you lose the
opportunity to tell the reader of the code what the variable contains
and what it is used for.
