That's really good that it's so dumb that you don't need to jump through hoops to think of the way to do it. Clever! Just code and go!
* Transforming a collection means doing boring for loops instead of one-liners. * interfaces/duck typing is great. But hey, []interface{} does not fit into interface{}. * Structs with fields are encouraged, but there is no uniform Uniform access principle and that sucks. * etc
But definitely, my own "science" confirms that it turned to be out less of a problem (for my own usage) compared to better languages with more friction.
