(Readded Phobos) I wrote a curry in std.functional which I think could
be a good starting point.

So is there a recommended way to approach arbitrary depth currying? std.algorithm only
allows one level. Bind was the only one I knew of that would allow me to
"nest" curries as deeply as I'd like to. Other ideas?
Thanks,

(Added Phobos.) We haven't tested std.bind in a long time. With the advent of
function literals etc., it seems pointless. Walter and I think it should be
deprecated.

Hi,
I've
been trying to get the simplest program that uses bind() to work with D 2.046
(or 2.036 or 2.047), but I've run into problem after problem. First, it
seems D2 tightened up const handling, and the NullAlias struct of type const
EmptySlot would match is expressions. After fixing that, I'm now
getting:
C:\Jason\D>dmd bTest.d
C:\tools\dmd2\windows\bin\..\..\src\phobos\std\binder.d(230): Error: alias
std.bind.Tuple!().Tuple.meta template identifier prependT is not a member of
alias meta
C:\tools\dmd2\windows\bin\..\..\src\phobos\std\binder.d(775):
Error: no property 'prependT!(T)' for type 'Tuple!()'
C:\tools\dmd2\windows\bin\..\..\src\phobos\std\binder.d(775): Error: alias
std.bind.dynArgTypes!(i,Tuple!(int),Tuple!(DynArg!(0)),1).prependType!(int,DynArg!(0)).res
cannot alias an expression __error
I'm a D newbie, and the
syntax is too much for to start on without getting a couple of practice programs
down first.
Do you know if anyone has tested std.bind in recent
releases? I've talked to Tom, but he doesn't seem to be supporting it,
esp. in D 2. I've also posted on DigitalMars.D. Any other
ideas?
Thanks,
Jason
