iz v0.6.18 - Now with a modern, fast, @safe, getopt-like function

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). - code: https://github.com/BBasile/iz/blob/master/import/iz/options.d#L596 - DUB: https://code.dlang.org/packages/iz - doc: https://iz.dpldocs.info/v0.6.18/iz.options.handleArguments.html - cool demo: https://github.com/BBasile/Coedit/blob/master/dastworx/src/main.d#L18 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).

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).

such attribute-based getopt is now used in styx driver e.g

here
here

In styx now I just do

if !getOpt![(session, DriverOptions, MachineTarget)](processCeeArgs(argc, argv), &onArgument) do
        return 1;

At some point we forgot what we wanted to do in D ;)
