I'm not sure how an object oriented approach would make things easier for schematic generation. The objects (components) themselves do not undergo much data interactions/manipulations. Maybe if you have some examples, this would be helpful for me to understand. As much as possible I am leaning towards a more functional approach, where inputs, data transformations and outputs are more defined.
With a new language, I could decide features that I wanted and more importantly, include more circuit specific features (branch/join/parallel statements). Of course, a python library would be able to produce the same data representation that circuitscript ultimately generates, but one aim of circuitscript is to make it much easier to do so.
The standard lib provides led, supply, res and cap as component functions (basically normal functions that return a component). For LED and supply, they take strings as parameters, this defines the led color and the name of the supply net respectively. Res and cap take a number parameter like 1k, 1u, 100n, etc. Such number expressions are very common in schematics and CAD packages, so this is a important feature to support (python equivalent of using 1e3, 1e-6, etc.).
