=head1 NAME

IRC::Mode::Single - A single IRC mode change

=head1 SYNOPSIS

  my $mode = IRC::Mode::Single->new(
    '+', 'o', 'avenj'
  );

  my $flag = $mode->flag;
  my $mode = $mode->char;
  my $arg  = $mode->param;

=head1 DESCRIPTION

A simple ARRAY-type object representing a single mode change.
These objects stringify into an IRC mode string.

Can be used to turn L mode ARRAYs
into objects:

  for my $mset (@$mode_array) {
    my $this_mode = IRC::Mode::Single->new( @$mset );
    . . .
  }

Also see L

=head2 new

Constructs a new mode change; expects at least a flag and mode.

=head2 char

The mode character.

=head2 flag

The '-' or '+' flag for this mode change.

=head2 param

The parameter attached to the mode, if any.

=head2 as_string

Produces a mode string (with params attached) for this single mode change.

=head2 export

Retrieve the backing ARRAY without bless/overload magic.
