Cast anonymous function argument

I can't seem to find any clear instruction on how to cast an argument to an anonymous function. I can cast on variable assignment, just not sure if this is possible and how.

Since I'm using lodash the typings define the argument as any but I need to cast it to a custom object, since in reality it would be.

_.findLast(this.children, function((CustomObject) node) {
  node.customMethod();
})

Blind luck led me to discover that (<CustomObject> node).customMethod(); works.

This should work

_.findLast(this.children, function(node: any) {
  var co = <CustomObject> node;
  co.customMethod();
})
