* Use string keys. I am still convinced we need BValue.
You mean something like this:
https://git.haiku-os.org/haiku/tree/headers/private/shared/Variant.h
?
However there's a big difference between OpenBinder's SValue and BVariant.
Note that in OpenBinder it's named SValue.
A BValue would be defined recursively as a key value pair, where both the
key and the value are BValues themselves. So, it can be thought of a
mapping (key->value).
It can of course contain a single value, and in that case, it can be
thought as a mapping everything->value. With this recursive definition, it
is possible to always think of it in terms of a map. I leave the
consequences and utility of something like that to the readers. But I think
it's rather obvious how this can be helpful in many ways in the HaikuAPI
(like for example messages) to make it more flexible.
