The show makes reference to "Midnight in Chernobyl" in its epilogue, I think it's safe to say it was one of the main sources of information for the show (though of course they took liberties because it was a historical drama).
I agree there are some claims in this article that should be further scrutinized but it's true that the levels of radiation were not as high as one might assume. The direction of the wind during and immediately following the disaster slowed the spread of radioactive material over Pripyat (this is also why southern Belarus was hit so hard). The prevailing winds in that region are north east and the Chernobyl power plant was on the north side of the city. By the time of the May day parade the winds had shifted such that Kiev was downwind from Chernobyl.
The KGB did their best to contain information about the disaster in general and the USSR wanted the May day parade to go on as-planned to make it look like things were fine. Even those with enough power or connections to be aware of the danger were pressured to participate. The May day parade was later often referred to in infamy by the Ukrainian independence movement following the disaster.
Most of my information comes from what I remember of reading "Midnight in Chernobyl" and "Chernobyl the History of a Nuclear Disaster"
It seems that in practice no it's not possible based on what I've read from people much closer to programming language design and compiler work.
"In practice, the challenge of programming language design is not one of expanding a well-defined frontier, it is grappling with a neverending list of fundamental tradeoffs between mutually incompatible features.
Subtyping is tantalizingly useful but makes complete type inference incredibly difficult (and in general, provably impossible). Structural typing drastically reduces the burden of assigning a name to every uninteresting intermediate form but more or less precludes taking advantage of Haskell-style typeclasses or Rust-style traits. Dynamic dispatch substantially assists decoupling of software components but can come with a significant performance cost without a JIT. Just-in-time compilation can use runtime information to optimize code in ways that permit more flexible coding patterns, but JIT performance can be unpredictable, and the overhead of an optimizing JIT is substantial. Sophisticated metaprogramming systems can radically cut down on boilerplate and improve program concision and even readability, but they can have substantial runtime or compile-time overhead and tend to thwart automated tooling. The list goes on and on."
It is truly risk free. You always buy the call using the customer's money but you only give them the call if every part of the parlay is correct. Assuming they charge a commission in addition to the asset price to cover transaction processing they shouldn't lose money
Edit: I don't really know how pricing these things usually works but I could see taking some risk on to price these attractively
