I'm not sure how it works underneath the covers, but I'm not 
currently working with a ton of templates explicitly. I am 
utilizing interfaces and some generic container types, which I 
guess might mean templates underneath. However, if an abstract 
class with a generic parameter translates itself to a template 
underneath the covers, I still would expect it to throw an error 
if I have a clear syntax problem. If it's not, that's pretty 
unacceptable actually for it not to.
