I was thinking about adding keyword argument support to pyd wrapped 
functions.

I don't know if this works any better:

https://github.com/jacob-carlborg/orange/blob/master/orange/util/Reflection.d#L29

It's a simple implementation.

I also have a function which also you to call another function using 
named arguments:

Neither of these two support delegate parameters.

Nice hack, but when using this on functions you don't control, be 
aware that parameter names are officially not considered part of 
the API (as it became clear in the named parameter-related 
discussions). This implies that e.g.  the parameter names of 
Phobos functions might change at any time.

Of course, this was more a "just because it's possible".

Hmm:

static if (is(typeof(func[0]) PT == __parameters))

__parameters is a new feature in is()' treasure vault, right?

Testing it, it seems to return the parameter tuple of a function.
That's cool. However, that'd be cooler if it was documented somewhere.
Was that in 2.060 changelog?

That should work nicely.

Why does it not show up on dlang.org?
