To be strictly accurate, Pyd takes the functions to be bound as alias 
template parameters. You wrap a D function with:

def!(functionName, "functionName");

The "def" template function has a number of template arguments but no 
function arguments. The above calls def with D's property syntax.

Pyd does not (yet) use .mangleof in any capacity. The function name must 
be specified explicitly as a string literal template argument.

As for deriving the various bits of a function pointer or delegate type, 
I suggest looking at the FuncMeta module in Tom S's Bind package. It 
currently lives here:

I am currently in the midst of thrashing Pyd until it uses that package.
