Let's summarize. Squeak doesn't handle proper an assignment to a block
argument and it is a bug. But anyway, assignment to a block argument is
considered bad practice so let's just forbid assignment to a block argument
thus get rid of the bug. That is "Scanner allowBlockArgumentAssignment:
false" is used for.

Is it right?
And does other ST implementations follow the same way? 
I've checked: Pharo2.0 does not allow and Pharo3.0 does allow assignment to
block argument.
VA Smalltalk doesn't allow changing block arguments (thanks Louis)
