  Recent spectroscopic observations of a d-wave-like gap in stripe-ordered
La(2-x)Ba(x)CuO(4) with x=1/8 have led us to critically analyze the anisotropic
transport and magnetization properties of this material. The data suggest that
concomitant with the spin ordering is an electronic decoupling of the CuO(2)
planes. We observe a transition (or crossover) to a state of two-dimensional
(2D) fluctuating superconductivity, which eventually reaches a 2D
superconducting state below a Berezinskii-Kosterlitz-Thouless transition. Thus,
it appears that the stripe order in La(2-x)Ba(x)CuO(4) frustrates
three-dimensional superconducting phase order, but is fully compatible with 2D
superconductivity and an enhanced T_c.
