@Alejandro Serrano Mena there are some small errors in the code examples in https://www.47deg.com/blog/arrow-analysis-kotlin-compiler-plugin/
• In the examples with the extension functions on List<Int> the dot is missing between the receiver type and the function name
• In the second extension function, fun List<Int>.firstOrZero() using isNotEmpty() the logic is the other way around (should be if (this.isNotEmpty()) this.first() else 0)

Looks good, but now the description of the function using isEmpty() has to be adjusted as well (2 lines above it still mentions isNotEmpty()) 😉

Also the text below has to be adjusted:
