Issue 8183 - template bug?

[Zhenya]

this doesn't work:

template bind(alias indeces)
{
     static if(is(typeof(indeces) : int[]))
     {
         auto bind(D,V...)(D dg,V values)
         {
             static if(is(D d : R delegate(U), R, U...) &&
                       is(V == 
Combination!(indeces,ParameterTypeTuple!D)))
             {
                 static if(indeces.length > 1)
                     return
bind!(update!(indeces,indeces[0])[1..$]).bind(Curry!(indeces[0])(dg,values[0]),values[1..$]);
                 else static if(indeces.length == 1)
                     return Curry!(indeces[0])(dg,values[0]);
             }
         }
     }
}

while this works :

class Bind(alias indeces)
{
     static if(is(typeof(indeces) : int[]))
     {
         static auto opCall(D,V...)(D dg,V values)
         {
             static if(is(D d : R delegate(U), R, U...) &&
                       is(V == 
Combination!(indeces,ParameterTypeTuple!D)))
             {
                 static if(indeces.length > 1)
                     return
Bind!(update!(indeces,indeces[0])[1..$])(Curry!(indeces[0])(dg,values[0]),values[1..$]);
                 else
                     return Curry!(indeces[0])(dg,values[0]);
             }
         }
     }
}
