If you're using Handlebars 1.3+, you can use a subexpression. First, write a string concatenation helper:

Ember.Handlebars.helper('concat', function (a, b) {
    return a + b;
});

Then use it like this (sorry, I don't know Emblem so I'm going to use the normal stache syntax):

{{t (concat 'dict.' item)}}
