In the manual, in section 2.1.1 Code Blocks: 
http://slate.tunes.org/doc/progman/node7.html#SECTION00041100000000000000
it says:
"Blocks furthermore have the property that, although they are a piece of code 
and the values they access may change between defining the closure and 
invoking it, the code will ``remember'' what objects it depends on, 
regardless of what context it may be passed to as a slot value. It is called 
a lexical closure since it ``closes over'' the environment and variables used 
in its definition, the lexical context where it was born."
Can anybody help me understand this ? what does the code block "remember" ?
Thanks.
