A SassScript object representing `#{}` interpolation outside a string.
@see StringInterpolation
Interpolation in a property is of the form `before #{mid} after`.
@param before [Node] The SassScript before the interpolation @param mid [Node] The SassScript within the interpolation @param after [Node] The SassScript after the interpolation @param wb [Boolean] Whether there was whitespace between `before` and `#{` @param wa [Boolean] Whether there was whitespace between `}` and `after`

13: def initialize(before, mid, after, wb, wa)
14: @before = before
15: @mid = mid
16: @after = after
17: @whitespace_before = wb
18: @whitespace_after = wa
19: end
Returns the three components of the interpolation, `before`, `mid`, and `after`.

Evaluates the interpolation.
