Last time i promoted my stuff here there were two
compiler/Phobos bugs preventing to activate this nice
getopt-like function.
specs:
- It's based on UDA.
- It supports multiple locations for UDA-fied functions and
variables.
- It doesn't use pointers, UDA-ified variable are accessed
without intermediary.
- It's faster than the phobos one (although getopt is never a
bottleneck)
- It's `@safe` and can be even `nothrow`
It could be easily added to phobos (just need to convert some
EnumSet to BitFlag).

Note that despite of the run-time compatibility mention in the
README, this module is part of a subset of IZ that can be used
without all the concept of Nogc as used in iz. (at some point i
should split the twos parts).
such attribute-based getopt is now used in styx driver e.g
-
[here](https://gitlab.com/styx-lang/styx/-/blob/master/src/styx/session.sx?ref_type=heads#L107)
-
[here](https://gitlab.com/styx-lang/styx/-/blob/master/src/styx/session.sx?ref_type=heads#L492)
In styx now I just do
```
if !getOpt, ) do
return 1;
```
At some point we forgot what we wanted to do in D ;)
