True, but sometimes you really do need them, particularly for complex library modules and certain kinds of complex data structures. I think using a collecting list after a "." will be rare, but when you need it, there's just no substitute. It can turn a deeply indented expression that forbids blank lines into a simpler format (and where blank lines end at a controlled point). And as you noted, they follow from the definition of <*...*>, so it would a surprise to the user if they are NOT allowed. --- David A. Wheeler
