looking at http://www.digitalmars.com/d/tuple.html it says:

"The data fields of a struct or class can be turned into an _expression_ 
tuple using the .tupleof  property"
(below that you find an example that actually uses it)

I tested it myself and it works. I actually use it to implement 
functions in a generic matrix struct.

But http://www.digitalmars.com/d/tuple.html (section Struct Properties) 
states:

".tupleof Gets _type_ tuple of fields"

I think that's a typo and should be fixed.
