Module eval 

Expression evaluation with automatic differentiation

Evaluates postfix expressions and computes derivatives using forward-mode AD.

Performance

For hot loops (generation, Newton-Raphson), use evaluate_with_workspace() with a reusable EvalWorkspace to avoid heap allocations on every call.

Modules

EvalWorkspace

Reusable workspace for expression evaluation.
