[Xotcl] proper way to access xotcl classes

[Matthew Smith]

Thank you for the help.

Now I am getting another error I don't understand.

invalid command name "my".

It seems like it is not getting to use XOTcl commands.  Here is what I have:
----------------------------------------------------------
package require XOTcl
::xotcl::Class Stack
Stack instproc init {} {
    # Constructor
    my instvar things
    set things ""
}
Stack instproc push {thing} {
    my instvar things
    set things [concat [list $thing] $things]
    return $thing
}
Stack instproc pop {} {
    my instvar things
    set top [lindex $things 0]
    set things [lrange $things 1 end]
    return $top
}

set s1 [Stack new]
----------------------------------------------------------
