How does one distinguish between an absent value and a value of null
(e.g., as a list element)?
In the current ForStatement:
"for (i, x in y)"
getIndexVariable() returns i (or null if "i," is omitted)
getValueVariable() returns x
getCollectionExpression() returns y
"for (int i = 0; i < n; ++i) ..."
getIndexVariable() returns null
getValueVariable() returns null
getCollectionExpression() returns a ClosureListExpression that contains
all of "int i = 0; i < n; ++i" — why it's called "closure list" must be
a legacy thing
How does this all work if more than one variable is defined?
