Yes I checked again and I do not get why it is barking with mark load it.
I will look at the plotmorph code later.

OCStoreIntoReadOnlyVariableError checks if you are compiling interactively or 
not.

signal
compilationContext interactive
ifFalse: [ ^ self crTrace ].
^ super signal

This way old code load fine, but you are not allowed to create such code while
coding… and you have to fix code when recompiling a method interactively
that has an assignment to an argument.

But using catalog, I can load plotmorph, even without enabling this setting.

Yes. But there is a setting for the compiler to load/compile code with
errors.

[Pharo-dev] Are assignment to block variables is prohibited?

[Stephane Ducasse]

Hi

I know that method arg are read only and you cannot assign to them.
Now what is the status of block arguments?
Because some old code of plotmorph is breaking.
