is this function lowkey okay?

pub fn parseCommand(comptime E: type, io: std.Io, args: *std.process.Args.Iterator, usage_message: []const u8) ?E {
    const arg = args.next() orelse {
        std.Io.File.stderr().writeStreamingAll(io, usage_message) catch {};
        return null;
    };
    return std.meta.stringToEnum(E, arg) orelse {
        std.Io.File.stderr().writeStreamingAll(io, usage_message) catch {};
        return null;
    };
}

I'm mostly concerned about the orelse expressions, doing catch {} seems odd, and returning null is also odd.

Could do a return type of !?E and just return the writeStreamingAll errors, but not sure.

The orelses and returning null seem fine to me

Catching and ignoring the error of writeStreamingAll to stderr is a matter of if you want to treat failing to write the usage message as a failure of the program
