Especially this one:
An API is intuitive if a semi-experienced user gets away without reading the documentation, and if a programmer who doesn’t know the API can understand code written using it.
IMHO The proposed API does not helps with all this and makes things very obscure for a programmer that is not fully familiar with the toolkit.
If I show this code to average C++ programmer the vast majority of them would not know what happens there...
The fact that you and 1 percentile of C++ programmers (that write Boost Libraries) understand the proposed code does not mean it is understandable to other.
But that's a general issue of C++ DSELs, not something new to this library. It is all about the expectations - most C++ programmers don't expect code that isn't imperative to do anything. Once you get over that misconception, I find that well-designed DSELs are very easy to read. That said, the original snippet is not well-designed IMO. The one that uses [] to delineate the contents of a widget is far better. Sebastian
