While it is highly unusual to implement linked lists in Tcl, since the language has a built-in list type (that internally uses arrays of references), it is possible to simulate it with objects.
<br>
<lang tcl>oo::class create List {
variable content next prev
constructor {value {list ""}} {
set content $value
set next $list
set prev ""
$next previous [self]
}
method value args {
set content {*}$args
}
method next args {
set next {*}$args
}
method previous args {
set prev {*}$args
}
}</lang>
