That was my original point. I would like a tool, as used to be the
Transcript, that has the same behavior than the stdout transcript but shows
the stream in the image instead of the command line.
In Pharo stdout is not broken. It works fine and I use it often. You can
start Pharo from the command line and try the do-it:
1 to: 100 do: [ :i |
0.1 seconds asDelay wait.
FileStream stdout << 'x'. ]
x is displayed every 100 ms on the command line.
Only the Transcript has a different behavior, which is not compatible with
the use cases of VM development.
