Metalinks in Pharo: https://www.slideshare.net/mobile/MarcusDenker/lecture-advanced-reflection-metalinks This is an elegant way of taking the AST of running code and attaching modifiers to it: logging, tracing, override (think advice or AOP). Pharo feels like the most open, dynamic language I've seen outside of f-expression based PLs.

Lecture: Advanced Reflection. MetaLinks

The document discusses advanced reflection techniques in Smalltalk, specifically focusing on the concept of metalinks, which provide a fine-grained reflective mechanism using abstract syntax trees (AST). Metalinks allow for dynamic behavioral reflection by linking metaobjects to AST nodes and defining execution control attributes, enabling features like logging and watchpoints without introducing recursion issues. The presentation highlights the practical applications and limitations of these techniques, suggesting ongoing development in Pharo to enhance functionality. - Download as a PDF or view online for free
