Issue 14606 [1] is tagged "Really Important" where evaluating....

    t1 := 1.
    t2 := 2.
    t3 := 3.
    t4 := 4.
    t5 := 5 .
    t6 := 6.
    [    t5 := 50.
         t6 := 60.
         t3 + t4.
         1 halt.
    ] value
=> can't see the value of t4, t5, t6.
I've just submitted a possible solution for this, but its a bit late
before release for such a change - so I'm asking for "all hands in" to help
stress test it.  You don't need to review code, just please merge latest
slice 14606 into your normal working image and report your experience.

Here is a minimal example that does not work with your fix. (condensed
from the failing test case)
[ :x :y |
    (thisContext tempNamed: 'x') inspect.
    (1 to: 1)
        do: [ :i |
            | k l |
            k := y.
            l := x.
            (thisContext tempNamed: 'x') inspect ] ] value: 1 value: 23
Both inspector windows should show the same value for the argument 'x'.
But the result is
1. inspector -> 1
2. inspector -> 23
Before loading the slice, both inspectors show â1â. That canât be right
eitherâ¦
No, that is correct. Both inspector inspect the block argument 'x', it is
assigned with value 1
with the message value:1 value:23
and the block argument value can not change, therefore both inspect should
show '1'
