Serhiy Storchaka added the comment:
Tuples represented in AST already are optimized at AST level. But there are
tuples created at compilation stage (see the code emitting BUILD_TUPLE).
Inada's PR 4879 simplifies the peephole optimizer.
I tried to move this optimization at the compiler level,
New submission from Raymond Hettinger :
Can the peephole optimizer's fold_tuple_on_constants() be moved to ast_opt?
It looks to me like there is sufficient information in the tree:
import ast
print(ast.dump(ast.parse('c = (50+1, 60+2)')))
