Date::strict - enable/disable date strict mode.
=head1 SYNOPSIS
    Date->new("invalid date"); # returns date with error set to Date::Error::parser_error
     
    use Date::strict; # lexical scope
     
    Date->new("invalid date"); # throws Date::Error::parser_error
    call_function_using_date(); # code inside function will not be affected by strict mode
     
    no Date::strict;
     
    Date->new("invalid date"); # returns date with error set to Date::Error::parser_error
    {
        use Date::strict;
        DateRel->new("1X"); # throws Date::Error::parser_error
        $date + "1X"; # throws Date::Error::parser_error
    }
    DateRel->new("1X"); # returns relative date with error set to Date::Error::parser_error
     
    Date->new("2019-01-32"); # ok -> 2019-02-01
     
    Date::range_check(1);
    Date->new("2019-01-32"); # returns date with error set to Date::Error::out_of_range
     
    use Date::strict;
    Date->new("2019-01-32"); # throws Date::Error::out_of_range
=head1 DESCRIPTION
By default, when any error occurs in L<Date> framework, it returns an empty object with C<error()> set.
This module allows you to enable date / relative date string mode when instead of setting error, it throws an exception with the same error.
This mode only affects code inside the same lexical scope.
This mode automatically reverts when the scope ends. If you want to disable strict mode in the middle of the scope, use C<no Date::strict>.
