If you are in the default frontend to Io, the language, and happen to revert to Smalltalk for a moment as in
CleverObj := KludgedObj clone.
and then find that you cannot recover without the offending ‘period’ with
CleverObj := KludgedObj clone
because now there is another error one line below the first …
Don’t panic!
Just enter
diddly
or
nil
or
whaddevvvah
and watch that error trump the previous exception.
Now you can happily clone again.
This seems to depend on the Win32 shell that I am running Io in, so you may never see this glitch …
