 my $list = Mail::Builder::List->new(Class name);
 OR
 my $list = Mail::Builder::List->new({
     type   => Class name,
     [ list => ArrayRef, ]
 });

This constructor takes the class name of the objects it should hold. It is only possible to add objects of the given type. It is not possible to change the assigned type later.

convert

 my $list = Mail::Builder::List->convert(ArrayRef);

Constructor that converts an array reference into a Mail::Builder::List object. The list type is defined by the first element of the array.
