Python is the canonical mainstream example: __init_subclass__/metaclasses (definition-time hooks) + __subclasses__(), mro(), __dict__ (introspection).
CLOS (Common Lisp Object System) also qualifies: defclass/initialize-instance/defmethod hooks plus runtime introspection of classes, generic functions, and method combinations.
Smalltalk similarly: class creation executes code, and everything is introspectable at runtime.
Languages that lack definition-time hooks (Java, C#, Go, Rust, TypeScript/TS-era JS) or lack sufficient runtime introspection for structural facts don’t meet both requirements without extra tooling.
Similarly I used to write Python on my Motorola Droid with the slide-out keyboard. But my touchscreen typing style these days relies heavily on auto-correct and trying to enter code is a real exercise in frustration.
You can store CO2 and sell it to construction companies (to cure ferrock), to energy storage companies (who like to put the CO2 in huge bubbles nowadays, go figure), or to agricultural corporations (who enrich greenhouses air in CO2 to accelerate growth).
I can't make sense of it mathematically. A statistical distribution fitting these characteristics does not exist.
If non-weeders have an average seat belt wearing, and if weeders also have an average seat belt wearing, then the proportion of weeders inside of the seat belt non-wearing class is just equal to the proportion of weeders inside the whole population.
Yes a parser is a fun to read ;)
