Within your template, this
refers to the current scope, so you can do:
{{ this[ 'item_' + variable_with_value_foo_or_bar ] }}
There are probably better ways to perform what you're trying to do, but hopefully this answers your question.
Frage
I'm new to AngularJS and I'm still exploring its possibilities. Currently I'm stuck with this problem: How can I name a variable using another's variable value?
For example I have something like this in my controller:
$scope.item_foo = 'Foo';
$scope.item_bar = 'Bar';
I can access the values with this:
{{item_foo}}
{{item_bar}}
So far so good, but now I want to display them dynamically. I have an object with 'foo' and 'bar' and I loop it with ngRepeat. How can I do something like that:
{{item_{{variable_with_value_foo_or_bar}}}} // should print Foo and Bar
Thank you for any of your help!

It seems like it would be better to use an object to store the data, rather than a bunch of things at the $scope
level...:
$scope.item = {foo: 'Foo', bar: 'Bar'};
// ...
$scope.variable_with_value_foo_or_bar = 'foo';
Then access with:
{{item[variable_with_value_foo_or_bar]}}
