Are you really storing a 'real' or a 'string'? (The default floating 
type in D is double, not real.) The following compiles and works as 
expected with dmd v2.069.2:

import std.variant;

void main() {
     alias Element =Algebraic!(real,string);
     auto r = Element(1.2L);
     auto s = Element("hello");
}
