How to declare a template type as parameter to functions

[Domingo via Digitalmars-d-learn]

Thanks again this second explanation now is easier to understand 
as general rule for this case and future ones that I'll face in 
the future.

I hope that this explanation would be added to the language 
reference where it explain functions:

With it there people will have a better understand right from the 
fundamental source of information.

Can someone add it there ?

Cheers !
