It is. But "#{foo}" was more in keeping with the OP's original code,
and I personally prefer to keep the length of call chains (as in
foo.bar.xxx.yyy.zzz) to a minimum. It ultimately amounts to
preference, IMO, as both are readily legible and easy to understand.
It's also exactly the same number of characters.
