 Priority:  normal       |   Milestone:  0.8.0   
Component:  scipy.stats  |     Version:  0.7.0

-------------------------+--------------------------------------------------
 some _isf functions are not implemented and calculated by 1-cdf

 we added several of them to improve numerical precision, but there are
 still some missing.

 a random check found gumbel_l_gen where the cdf is implemented as
 1.0-exp(-exp(x)) but _isf is not implemented.
