I miss Visual FoxPro. I have never been more productive in my whole life. Of course compared to today's languages that's an abomination to say, but the tools, the data browser and the sql embedded in the language made it shine on its own merits.
Now tools, they were unbeatable in their simplicity and effectiveness as you say. A data browser is the most powerful UI and the ability to connect it with a data source by its cursor name can't get any simpler. Try doing that even in Swift and it is a rain dance of sorcery to make it work.
A data source to a report, bam! As simple as that. A data source to a table, bam! to a form, bam! to any UI control, bam! That was productivity if I've ever seen it.
