Hi, (This is great language, sincere thanks to all!) I took a quick glance of https://devguide.python.org/langchanges/ (20.3. Suggesting new features and language changes), while writing this post. Please ignore this, if similar proposals are discussed earlier. Suggestion: 1. Big Set, Big Dictionary - During design time, i am considering this question. With limited RAM (example 4 GB), how can I store a dictionary/set of size greater than RAM. Is it possible to introduce Big Set / Big Dictionary which stores data in hard disk (based on some partition mechanism - like big data)? (i.e.Big Set/Big Dictionary with set access mechanism identical to current set and dictionary). Background: I am working on machine learning NLP and would like to use such feature in data generator.
