I've had a good poke around the forums and couldn't find anything on this so ...What's the recommended method for dispatching code off the runtime type of a variant variable (Phobos D2 std.variant)? Does one use a bunch of if ( var.peek!(type1)) { ... } else if ( var.peek!(type2) { ... } for all N possible types, or is there a better & faster way with a switch or jump table of sorts?
Variant should have an accessible typeinfo property. (When I say should, I mean that it would be appropriate for it to have it. I am not saying that I believe it has it.) It should be faster to compare that (or switch on typeinfo.name) than to peek for each type.
