…#1007) The replacement wrappers for exec(), eval(), and compile() break the implicit compiler flag inheritance chain. When code with `from __future__ import annotations` calls exec() with a string source, the wrapper recompiles it without the annotations flag, causing type annotations to be evaluated at runtime instead of being kept as strings. Fix all three wrappers to extract __future__ flags from the real caller's code object and pass them explicitly to compile() with dont_inherit=True. Fixes #1007 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
