Hmmm, well easy starting html then you could do CSS or JS to go with it.
Python's lambda was never intended to be a full feature:
Or in other words, van Rossum deliberately broke lambda because he hates the whole idea and was dragged kicking and screaming into having lambda by his users, who of course want it. You don't often see a language designer make the language defective on purpose, but anything that can happen, will. :~(
I eventually want to get PyPy, (Python written in Python) mainly to fix lambda.
