The first mechanism that PBMs use is formulary leverage. Drug manufacturers that want preferred formulary placement—or to avoid exclusion from coverage—must offer better prices. That leverage for PBMs depends on a credible threat: lower your price or lose access to patients.
This is really powerful for writing a lexer and parser that work together without having complicated code, or by storing an entire intermediate result in memory before passing it to the next stage. The lexer can trundle along and once it’s got a full token it can yield() that value. The parser just continually runs .call() whenever it needs a new token to process. They’re passing off control between each other in a more complicated way than just calling a single function and getting back a single result. The code in the lexer and parser can be more freely structured as any function can yield() or call() whenever a value is found or needed.

But we also take this position with some regret, because the current conflict is another example of the failure of the international order, despite decades of UN security council resolutions, the work of the International Atomic Energy Agency in a succession of sanctions and diplomatic frameworks, Iran’s nuclear threat remains, and now United States and Israel have acted without engaging the UN or consulting with allies, including Canada.
