XOTcl is exotic too ;)

Object isobject $var && $var istype MyClass
 
Perhaps "hasclass" is better for you.
Consult documentation for a difference.
After I have started to use mixins so time ago, I have to adapt all istype to
hasclass.
 
proc isObjectOfType {obj type} {     expr {[Object isobject $obj] && [$obj
istype $type]}
}
 
Could be defined as Object proc
