Yeah, that's a little hole in the grammar, but there are ways:
// Declare an alias:
alias aliasOfInt = aliasOf!int;
// And use that:
assert(!aliasOfInt!string);
Or use std.meta.Instantiate:
assert(!Instantiate!(aliasOf!int,

does not have property 'isAliasOf
Yeah, that's a little hole in

The first version works here:
```
template aliasOf(T) {
enum aliasOf(alias a) = is(typeof(a) == T);
}
string s;
pragma(msg, allSatisfy!(aliasOf!string, s, "string"));
```
I can see that my description was a little confusing,

Eg:

The use case for this is for std.meta.allSatisfy for variadic
args, i.e.
template T(values...) if (allSatisfy!(aliasOf!string, values) {
... }
But how do you
