How do I index an `AliasSeq` with an integer known at run-time?
With a `switch` that has a `case` for every possible index:
----
import std.meta: AliasSeq;
alias seq = AliasSeq!("foo", "bar", "baz");
string f(size_t rti)
{
sw: switch (rti)
{
static foreach (cti; 0 .. seq.length)
{
case cti: return seq[cti]; break sw;
}
default: break sw;
}
return "";
}
