@jankrems @BRMatt auto-flattening makes result M[String] but I expected M[M[String]] (I'm writing generic code; don't know what M is)

@puffnfresh As I said: on that abstraction level I agree. But practical example where specifically auto-flatMap of promises fails..?

@jankrems x.map(makeRequest) // my other function expects M[Promise[String]] but get Promise[String] - breaks.

@puffnfresh I was talking about specifically flatMap of promise chains. When using .then - not a theoretical .map

@puffnfresh So my question would be: could there be any function that expects Promise[Promise[T]] for good reasons?

@jankrems @puffnfresh without abstraction, even the slightest, there is no longer any point to the API. It's entirely rubbish.

@dibblego @puffnfresh Well, imho an abstraction for its own sake without practical value is rubbish. PLs are tools in the end.

@dibblego @puffnfresh I'm not saying that an additional generic .map/.flatMap wouldn't be potentially valuable.
