I'm making a template to handle multiple accesses to the same

realize how much code is going into just forward referencing to
things based on certain states.
I have the following head template (there's about 5 total with
how I see it):
template multiAccess(Type, string name, string attributes,
choice, bool read, bool write, T ...) {
static assert(T.length % 2 == 0,
"Must be in pairs, AccessName & matching Value");
//eponymous enum
enum multiAccess =
multiAccessFunctions!(Type, name, attributes, choice,
read, write, T);
}
I'm calling it with:
int choice;
int a = 100;
int b = 200;
int c = 300;
writeln(multiAccess!(int, "test", "@safe nothrow pure",
choice, true, true,
a, 0,
b, 1,
c, 2));
And I'm getting the error of:
Error: template instance multiAccess!(int, "test", "@safe
nothrow pure", choice, true, true, a, 0, b, 1, c, 2)
multiAccess!(int, "test", "@safe nothrow pure", choice, true,
true, a, 0, b, 1, c, 2) does not match template declaration
multiAccess(Type, string name, string attributes, choice, bool
read, bool write, T...)
Maybe something obvious but I'm not seeing it.
You appear to want "choice" to represent a value, rather than a
type.
Declare it as "int choice" or "alias choice"
Not that with "int choice", you'll get a compiler error because
it isn't a compile constant. I'm not really sure about how
"alias" works, but that's the source of your problem.
