What's the correct way of implementing formattedRead support for
user-defined types? I tried overloading the unformatValue() template,

Unfortunately, there is not yet general way. The definition of unformatValue for user-defined type in different module isn't considered by std.format module. D's module system is closed in basic. Kenji Hara

Maybe do you want to open this discussion in the main D newsgroup? I think this is not a very important issue, but it's a nice thing to have. Bye, bearophile
