Hi !
Tried to find
alias Typeof(alias A) = typeof(A);
or something, but failed.

Are there something or should I create a PR to phobos?
Thanks

I have UDAs with values à la  (`str`, 123) uint k;

And i want to know a type of a value.

How are you using those? typeof works with any value:

void main() {
      (`str`, 123) uint k;
     foreach (a; __traits(getAttributes, k)) {
         pragma(msg, typeof(a));
     }
}

Prints

string
int

You can use indexes with the loop as well:

     foreach (i, a; /* ... */

I don't know if Typeof is actually needed for what the OP is trying to do,
but if you wanted to apply typeof using something like std.meta.staticMap,
then you'd need something like Typeof.

I see.

Just to add something that I've just remembered, it is possible to apply 
typeof to __traits(getAttributes) as well:

     foreach (T; typeof(__traits(getAttributes, k))) {
         pragma(msg, T);
     }

Now we get a list of types:

string
int

If it were in Phobos, I'd expect it to be in std.meta, and it's not there.
