Just if anybody wants / needs to know how to modify @Krux02 original code to
automatically use a converter and therefor hiding more of the implementation
details.
Simply replace the lines from `let castIdent = ...` to the end of the file with:
# instead of let castIdent = ...
let converterIdent = newIdentNode($interfaceName.symbol & "Converter")
result.add quote do:
converter `converterIdent`(this: var `implementationCandidateName`) :
`interfaceName` = `interfaceName`(
objet : this.addr,
vtable : `vtableValueSymbol`.unsafeAddr
)
The example can simply call `foobar(a)` and `foobar(b)` after this modification.
