Yes, it's possible. Depending on what you want to do, you can do it the 
C++ way, with a series of templates; or for just linking you can use the 
.mangleof property. Look up 'PyD' for bindings to Python with a syntax 
like that.

No, you can't find the members of a class or struct at compile time. Not 
yet, anyway. At run time you can use DDL (at dsource).

BTW -- You keep making a spelling mistake, it's time someone corrected 
you. "bee" is an insect that buzzes and makes honey. The word you want 
is "be". <g>

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:

http://www.mat.uni.torun.pl/~h3r3tic/bind.rar

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

Thanks for pointing me to the bind package (I did know about the pyd 
alias thing) as for the mangleof property is their complete 
documentation somewhere the d abi page had some TBDs in it.

There's no documentation, but see my meta.demangle and meta.nameof 
modules in DDL on dsource; I believe it covers 100% of the cases 
(std.demangle misses quite a few). If you find something it can't 
demangle, let me know!
But seriously, you probably don't need anything other than meta.nameof.
