Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for non-Python developers

   API requires Python-specific patterns, such as context managers and decorators, which may be unfamiliar to those without extensive Python experience.

2. 02

   Frequent breaking changes between versions

   Historical updates from v0.1 to v0.2 and beyond have introduced significant API changes, requiring substantial code refactoring for existing projects.

3. 03

   Limited integrations with non-Python tools

   Being a Python-specific library means that it does not integrate easily with other languages or frameworks without additional development effort.

4. 04

   Complex setup for advanced features

   Setting up syntax highlighting, auto-completion, and multi-line inputs requires significant configuration and understanding of the library's architecture.
