Dear All,
As explained in the above quote, it may be reasonable to display stderr
in the shell (and possibly other) src blocks upon execution.
+ Stderr may contain important information even if the code block
succeeds
- Displaying stderr will raise *Error* buffer, which may or may not be
expected or desired.
What do you think?
