I don't think the format is sufficient for recreating the array:
import std.variant;
import std.conv;
import std.stdio;
struct S
{
int i;
}
void main()
{
auto a = [ Variant(42), Variant("hello"), Variant(S(5)) ];
writeln(a);
}
Outputs:
[42, hello, S(5)]
We can only guess that 'hello' is a string but what if it were the
string "43"? It would look like an int. Also, any type can overload
toString; so, S(5) could output itself as e.g. "world".

This requires a serialization module. std.serialization is in review
right now:

Its author Jacob Carlborg already has a serialization module called Orange:
