Heh, that was the first thing I asked for on the GitHub issues list. :)
See: https://github.com/apolukhin/magic_get/issues/47 <https://github.com/apolukhin/magic_get/issues/47>
Thereâs an example in that issue for how to create your own version - not for specializing each of your types exactly, but rather re-implementing a bit of PFR's streaming code in your own namespace.
Once you do that, you can do whatever you want - including handling your own custom types and your own customization-point model (i.e., by implementing template specializations, or custom function names, or tag-dispatching, or whatever).
I used it for making `bool` types print âtrueâ or âfalseâ instead of â1â or â0", for example - instead of having to pass `std::boolalpha` into `std::ostream` _everywhere_.
