It's not just the arcade machine implementation. The owners of these companies want to go all the way and move everything to data centers so they can rent compute time, similar to the idea of the time-sharing days of the 60s.

Most applications backed kdb+ do just this. It comes with its own parser and you can query tables using something like an ast. For example the user might ask for data with the constraint where TradingDesk=`Eq, AvgPx>500.0 which kd

We do this in q/kdb+ systems often for patches. An important thing about these languages is that this kind of workflow is part of the core for solving problems. So when you are building a system one of the aspects of its design will al

In 2021/2022 there were 60 people in the UK who probably fall into that last group. Together their taxes accounted for about 1.4% of the UK tax bill despite being something like 0.002% of the population.
