Feature or enhancement
Proposal
I have implemented a stack-based version of ast.literal_eval and conducted benchmarks to compare its performance with the existing implementation. The results indicate that the stack-based version may improve performance on non-nested expressions, although it is slightly slower on nested expressions.
Benchmark Results
The benchmarks were conducted on an Intel(R) Core(TM) Ultra 9 185H. Below are the results comparing ast.literal_eval and stack_literal_eval:
Question
