in D1.0

template(T if typeof(T.init + T.init) == T)

or in D2.0

template(T if __traits(compiles, T.init + T.init))

I could mess something in above examples, but as you can see, getting it 
to work is not a problem of my syntax for templates. It is just a matter 
of using proper syntax for compile time reflection.
