       Please contact me if you find bugs or otherwise improve the module. More tests are also very welcome !

       This class provides a way to write a value returned by Perl code into a HTML field.

       new NAME, CODE
           Creates  a  new  value which will correspond to the HTML field "NAME". The "CODE" is a code reference
           that will return the value to be written into the HTML field.  The code reference will be called with
           two parameters, the object and the HTML::Form::Input object.

       name [NEWNAME]
           Gets and sets the name of the HTML field this value corresponds to.

       value FIELD
           Returns the value to put into the HTML field.

   EXPORT
       None by default.
