proposed sign for path integrals

Could someone please design an integral sign that looks like a Cornu spiral? i.e. the usual \int but with curly ends. Typed in LaTeX as \intc, it could go in the esint package or amsmath. It would signify a path integral in physics. \intc_a^b \exp{iS[x(t)]}{\cal D}x(t) would signify taking a sum over all paths from point a to point b. Right now one uses just \int_a^b, but it's not a Riemann or Lebesgue integral.
