Thanks to ECMA6 this is now only 73 bytes, and makes more sense to call.
You can now follow the pattern shown here;
var temp = curry(fn, scope, arg1, arg2)(arg3);
temp(arg4, arg5)(arg6);Additionally if you don't need a scope argument it can be reduced to 64 bytes:
a=(b,...c)=>c.length<b.length&&((...d)=>a(b,...c,...d))||b(...c)Golf'd.
