I enjoyed Jeremy's post about Oslo.
In the comments, there were lots of follow-up questions about the realness and substance of Oslo, and the target customers of the language. Here's some reflections from one Oslo guy...
What we shipped in our first CTP is very much an early alpha of our bits. And, it represents the lowest level of the platform without many of the services, libraries, and bells-whistles that you'd want as a developer. It's as if we shipped the .Net runtime and C# but without any libraries or tools. So, that may be some cause of confusion.
Why did we do this? We wanted to get out the core of the platform as soon as possible so we could start having real discussions with customers and partners. We also want the developer community to embrace modeling as a key principle in the future for how we build applications.
Ultimately, our goal is to enable declarative, model-driven programming. If I look around, I see people doing this today in the form of XML schemas and dialects, various textual reps, and frameworks that encode a domain. We went down that path as well, using visual designers and XML. But at some point the pain was too much :) We evolved our approach into Oslo by trying a more holistic solution. We wanted an easy-to-use language to write down declarations. We wanted a place to store those declarations, and then query, and even compose that data (i.e., join) into "instructions" that runtimes could execute to produce interesting behavior. And then, the idea of making it very easy to create a textual DSL over the model/declarations seemed like a natural step forward to enable app development in an elegant way. It just all fit together for us - and we wanted to share as soon as we could.
Let me also comment about our target customers. We are all developers on our team, and we care deeply about developer tools and productivity. We do not really talk much about making business users programmers. I have to say that personally, I think having a DSL may make it easier to have interesting conversations with business users about the solutions that we build for them. But I don't think that makes them programmers. It just makes it easy to write things down and share/design it with them.
...end of reflecting for now.
