Yes, you can have the same field name in different records, and the
positions need not be the same, as in

	record foo(a,b,c)
	record baz(c,b,a)

Icon will handle this properly.

Also, as you've observed, the "name spaces" for identifiers and field
names are disjoint, so you can, for example, have a local identifier
named b and do something like

	b := foo()
	   .
	   .
	   .
	b.b := 1

(Not recommended, of course.)

And a record need not have any fields, as in

	record nil()

Useful if you need objects of an identifiable type, but the objects have
no attributes.
