this isn't public API. why does it have a pimpl at all? i think some people have missed the point of the FooPrivate classes: maintaining binary compatibility in publicly exported APIs. for anything else they are just a bit more overhead, one more level of indirection and one more opportunity for a memory leak.

> The Ion makes use of wetter.com's officially-supported REST API. The API supports forecasts for up to three days, so the Ion does not supply any information about the current weather conditions. The forecast for the current day is split between night and day whereas the following two days are provided as an aggregated value for the whole day, respectively.

Profiled it for memory leaks using Valgrind, which did not bring up any leaks in the control of the Ion. Those two still look somewhat suspicious, so I'd like to get your opinion about them:
