No, that wasn't the point. When normally creating an object you
can call other methods along with the initialisation procedure
(this is mentioned in the section of the tutorial about parameters,
IIRC). So the following works:

Class Foo
Foo instproc init {arg} {
  puts "arg: $arg"
}
Foo instproc anotherMethod {param} {
  puts "param: $param"
}

set foo [Foo new initArg -anotherMethod methodParam]

Output:
param: methodParam
arg: initArg

This can often be extremely handy (and a nice feature of XOTcl). But
apparently this does not work with [next] and init. It's not exactly
documented that it doesn't work, but it would feel natural to assume that.
