[issue21074] Too aggressive constant folding

[Nick Coghlan]

Nick Coghlan added the comment:

I'm marking this as a duplicate of issue 11549 (which is about building out an AST optimiser), mostly because I don't think this kind of parameter tweaking makes sense with the current peephole optimiser.

With a more sophisticated Python implemented optimiser earlier in the pipeline, it becomes more reasonable to make smarter decisions about space/speed trade-offs when dealing with sequence repetition, and even just really large integer values.
