what do you think of the proposal to define the bisect operation with
the splitpoint as a parameter ? then eithr midpoint or flmean or any
interior point can be used.
If we offer a default, flmean seems to be a good choice


There is no good default.

flmean has serious deficiencies for splitting [0,1],
while the midpoint has serious deficiencies for [1,1e12].
