I start with foxpro/visual foxpro. I still think was the MOST productive environment, bar none, for complete, end-to-end app development (for desktop).

I still miss it. I work with Delphi and later python (I like so much python) but still feel cheated by how much extra work is necessary.

I'm dreaming in a new language that mix python/foxpro and have sqlite integrate directly, so database and app development were as natural as with fox.

I still consider the Visual FoxPro REPL and debug window THE golden standard! NO even iPython is superior. It was so out-your-way and dam practical (you can use it directly from your own apps!, talking about easy solving on your running apps)
