Why mixing interpolation and expressions is bad practice:
It increases the complexity of the markup
There is no guarantee that it works for every directive, because interpolation itself is a directive. If another directive accesses attribute data before interpolation has run, it will get the raw interpolation markup and not data.
It impacts performance, as interpolation adds another watcher to the scope.
