No. It wouldn't make sense to, since it's not an instantiation of 
the template and thus there are no template arguments. Basically, 
aside from ddoc, this should be the same as if the unittest block 
were outside of the template, but by having a unittest block 
inside of the template, it can be immediately after the function 
that it's testing, allowing it to be used for generating the 
examples for ddoc as well as making it easier to find and 
maintain the tests that go with each function.

It would be kind of like how with a static function in a 
class/struct, you don't have access to the this 
pointer/reference, since you're not dealing with an actual 
instance. Only in this case, it's the template arguments which 
you wouldn't have access to, not the this pointer/reference, 
because you're not dealing with an actual instantiation of the 
template.
