Like `std.json.JSONValue` or `std.variant.Variant` you can also 
use a struct with a type flag and possible data types that fit 
for you. Boolean and Integer may share the same memory location 
via `union` for example. Or just use the built one `Variant` type.

In case you only store the pointers to the data, you just need 
`void*[]` and proper casting.
