I don't understand the following behavior for a simple S3 class. The
auto-printing at the command line
doesn't behave as I expect. I'm probably missing something, but it might be
a bug.

> print.testClass <- function(x, ...) cat("Class:", class(x), ":", x, "\n")

> structure(1, class = "testClass")
Class: testClass : 1

> print(1 * structure(1, class = "testClass"))
Class: testClass : 1

> 1 * structure(1, class = "testClass") # why doesn't auto-printing call
print.testClass here?
[1] 1
attr(,"class")
[1] "testClass"

> structure(1, class = "testClass") * 1
Class: testClass : 1
