this is the exact problem with this naming scheme!

I fear I have to disagree, but I think it's not a good idea.

in this case only ITemplateEngine would be an interface, the other two 
would be classes.

add the implemented interfaces to the file name. That would lead to 
problems if you change which interfaces a class implements.
