[Python-Dev] The docstring hack for signature information has to go

Can you summarize why neither of the two schemes you tried so far worked?
AFAIR the original scheme was to support the 3.3-compatible syntax; there
was some kind of corner-case problem with this, so you switched to the new
"sig=..." syntax, but obviously this has poor compatibility with 3.3. Can
you remind us of what the corner-case was? How bad would it be if we
decided to just live with it or if we added a new flag bit (only recognized
by 3.4) to disambiguate corner-cases?
