# ONNX Script Roadmap
* Improve error-checking and error-handling to identify use of unsupported
Python features/constructs as early as possible and report it.
* Improve documentation and tutorials
* Features
- Support nested functions, for use as sub-graphs in ops like Scan
- Generalize support for _break_ statements in loops
- Support indexing notation for slicing/gather/scatter operations
- Improve type-annotation support, especially for tensor shapes
- Improve support for non-tensor types (sequences, maps, and optional)
- Improve checking in eager-mode to ensure its semantics is aligned with ONNX semantics
- Support for variadic inputs/outputs
