doc bug on Tcl link command

On page https://www.tcl-lang.org/man/tcl9.0/TclCmd/link.html
There is an example class Ex that ends with these lines:

set o [Ex new]
$o 3 5 7
        → This is a
        → This is b(3)
        → This is c(5,7)

but when I tried the example I got:

unknown method "3": must be a, b, c, call or destroy
    while executing
"$o 3 5 7"

When I did `$o call 3 5 7` it worked as expected.

There's no link on the page to edit it or to report a bug
in it so I thought I'd write here.
