I continued work on adding methods to existing data structures, and improving others.
- Added list repeat (1888). Fixed warnings from a couple of other functions
- Fixed an issue to disallow zero step in list, string slicing (1879).
- Completed work for 1845 - there was an issue in popping from nested iterables
For the next week, I plan to work on known issues. This includes
- Supporting nested tuples (1886)
- List index with optional arguments
