annotate text signatures in docstrings, resulting in fewer false positives. "self" parameters are also explicitly marked, allowing inspect.Signature() to authoritatively detect (and skip) said parameters. Issue #20326: Argument Clinic now generates separate checksums for the input and output sections of the block, allowing external tools to verify that the input has not changed (and thus the output is not out-of-date).
