Yeah, now that closures work, you could effectively curry the values:
| block w z |
w := 3.
z := 12.
block :=
[:captureW :captureZ |
[Transcript show: captureW asString , ' ' , captureZ asString; cr]]
value: w value: z.
w := 0.
z := 1.
block value. "should still show 3, 12"
There might even be a method for that... or it might have just been
Seaside specific.
In fact, that's sorta what fixTemps did before. :)
