Hello,

For blockClosures it is normal, block closure arguments have always been assignable since smalltalk-80. We could add a warning to discourage it, but we cannot forbid it, or we will not be able to load lots of frameworks and libraries that use it. So�12419�is not a bug to me, it's a feature.

For methods it is a bug, thanks for noticing. I will check.

similiar to issue 12419� block arguments should be read only

Indeed, I can compile:

C>>foo: arg
� � � � ^ arg := 3

And 'C new foo: 1' returns 3...
