Thanks for taking over on the final bits Michael, I appreciate it. I was
mostly concerned with the expect tests themselves, as I'm pretty weak
WRT expect/dejagnu. If the testcases are ok in regards to this, then
I'll proceed to add further testcases in the same style. I'll probably
add a series of try/catch tests, and then go through and add test for
derivation and more visibility-type tests for derived templates.

Thanks for your help.
