I've also tried to create a some sort of 'bind' function which could
let you bind arguments to specific parameters of a function. If I had
it working it would really help (me) out in coding for e.g. the
Windows API. For example you might have a WinAPI function such as (I'm
pseudocoding here):
CreateWindow(int x, int y, int w, int h, int* opt1, int* opt2, int*
opt3, char* name);
And if you want to create a certain type of window with some
parameters which are always the same, you could create an alias that
binds certain arguments to this function:
alias bind!CreateWindow(void, void, width, height, null, null, null,
void) myWindow;
Here 'void' would designate arguments that you would have to fill in
when calling myWindow.
You would call it like:
myWindow(posX, posY, "MyWindowName");
which would translate the call to:
CreateWindow(posX, posY, width, height, null, null, null,
"MyWindowName");
I don't see the point reviving the std.bind module*. In your case a
new function name 'myWindow' needs to be defined, which makes it
easier to just create a wrapper function
auto myWindow(int x, int y, char* name) {
return CreateWindow(x, y, width, height, null, null, null, name);
}

I absolutely agree, also creating delegate in place solves pretty much
all of std.bind use cases.
