In Python, when you write if x > 5: print("big"), you’re using special syntax baked into the language. You can’t change how if works. You can’t compose it, pipe it, or partially apply it. You can’t pass if as an argument to another function. But what if you could? What if if, for, while and even fn and var were just regular functions? In languages like REBOL, Red and Rye they are. ...
If you’ve ever filtered a CSV in Pandas or written multiple nested for loops to group data in Python, you’ll probably find Rye’s take on the problem interesting. Rye is a small, homoiconic language inspired by Rebol and Factor. One of its most interesting value types is the Table. A first-class, immutable data structure for tabular data. Tables are mostly manipulated with pure, composable (endomorphic1) functions. By using Rye’s pipe and op-words, common wrangling tasks become small, chainable expressions. ...
