Description

Our semantic analysis now strictly enforces that tensor dimensions match exactly during assignment (e.g., Tensor<f64> vs Tensor<f64, [4, 4]>). This is a breaking change for .vx programs that previously relied on implicit or lax shape propagation.

Action: Formally document this behavior in the README.md or language specification document. Decide whether implicit casting or broadcasting rules should be implemented in the future.

Research direction

Start with README.md or the language specification and review the semantic analysis behavior described in the issue. Document that tensor dimensions must match exactly during assignment, including the Tensor and Tensor<f64, [4, 4]> example, and record the future decision about implicit casting or broadcasting rules.
