Hi, Young-Jin Lee,
Your guess is exactly correct. Workspaces assume that any otherwise- unknown variable is intended to be a "workspace" variable.

Hi,
I am a newbie trying to learn Squeak. The squeak book and tutorials says that I need to define a local variable using a pipe like below:
| someMuppet | someMuppet := Muppet new. someMuppet name: 'Elmo'. someMuppet greet.
But when I tried the same code without defining a local variable shown below, I got the expected results, which makes me wonder when I should define a local variable.
anotherMuppet := Muppet new. anotherMuppet name: 'Gookie Monster'. anotherMuppet greet.
My guess is that I need not define a local variable if my code is being executed within a Workspace because all variables such as anotherMuppet will have "Workspace" scope.
Can anyone please explain in more detail about variable scopes?
Thanks in advance.
