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.
Yes, and using $month for the keys 'english' and 'french' does not
really do that. Perhaps using $language would have been better?
