I find that the feature to get a particular property (`--data=X`) is very slow, is it normal ? On a decently recent machine it takes something like 3 or 4 seconds. Maybe it downloads or check the deps while it's not necessary ?
It still has to do all the usual processing to read dub.json/dub.sdl and build up all the package information for the current package and all dependencies. Should be about the same as plain old "dub describe".
I suppose for some information that might not be strictly necessary, but I suspect that adjusting dub's package-information-gathering to be more lazy might take some major refactoring. And I'm not sure how much that would realistically gain in typical real-world scenarios.
If you need multiple pieces of information, you can specify `--data=X` multiple times in the same call to dub. Or a comma-separated list: `--data=X,Y,X`. That way the up-front processing would only be needed once, and not repeated for each piece of data.
