If a developer doesn't assign an id or name to a link the method show_all_objects() of class IE, doesn't provide much info about the link. I think this method should be modify to output the text and url of a link object, at the very least.
Check out the output, of ie.show_all_objects(), below:

1. radio name=rd1 id= value=No alt= src=
2. name= id=
3. name=ptisLink id=ptis2
4. radio name=email_frequency id= value=daily alt= src=
5. radio name=email_frequency id= value=Weekly alt= src=
6. radio name=email_frequency id= value=monthly alt= src=

Lines 2 and 3 represent links on the page.
Link in line 2 was not assigned a name or id attribut.

Also the name (or type of the control, i.e. button, radio, text field) of controls of type link is not being listed, unlike 'radio'.

Thanks for looking into this.
