Hallo!
Is it possible to create arrays which has more then one type,
f. ex. array[0] = 1; array[1] = "z"; array[2] = new clazz(),
....
I tried "Variant", but it slow down heavily my app.
Greetings,

It's always going to be slower. To do this, every access to the
array has to come with some amount of branching and/or and
indirection (including an indirect function call if you do it the
OOP way), which all have a cost, not to mention obstructing
optimisation by the compiler.
It's possible that std.variant.Variant isn't as fast as it could
be, but it's never going to be even close to
zero-performance-cost.
