Thanks for clarifying that! It was my guess that the "" was forcing $foo to be interpolated into the string before the substitution operation was performed on it.

    What interpolation???

    In short:

    In the first snippet, you are concatenating $foo with $foo, so that's what you get.

    In the second snippet, you are concatenating something derived from $foo and $foo, so that's what you get.
