Better way to select randomExhaustive() stochastic values

Input a list?
If list isn't long enough take values over and guess the rest
If all else fails go with default values

Start by locating the randomExhaustive() implementation in the Python framework and read how stochastic values are currently selected. The issue proposes accepting a list, reusing values when it is short, guessing remaining values, and falling back to defaults; confirm these rules before defining what done means. No specific file or test is named.
