This idea only struck me a few minutes ago, so it is probably
worthless, but anyway:

One of the places one does not explicitly use a program fragment is in
the control portion of a for loop.  One still writes:

	for (var in list) { ... }

rather than

	for var { code to generate list } { ... }

or whatever.  I realize one can transform from one to the other fairly
easily in es, but the discrepancy remains.
