Hi,Since IFormattable is deprecated, how can I override the structured formatting behavior for a specific type?The concrete problem is this: FsCheck prints all arguments using any_to_string or printf "%A". However, to print function values, I've added a Function type in which I keep the arguments and results that a specific function has been called with; but I'd prefer to change the strucutred formatting of the Function type. I can override ToString, but any_to_string does not pick that up; and using printf "%O" does not pick up structural formatting if ToString is not overridden. So the (ugly!) workaround it to change my output functions to special case the Function type, and use %O instead of %A in that case. Yuck.So what's the deal? How can we get the benefit of default structural formatting, _and_ the ability of overriding its behavior?This is somewhat related to:[link:cs.hubfs.net] the suggestion was to use fsi.AddPrinter, but that doesn't work for me since I want to customize the output of the type no matter what the context.cheers,Kurt
