Comment(by dustymugs):

 I think the ideal solution (at least for all the functions I've written)
 is to eliminate the "hasnodata" function argument.  If a band is flagged
 as having nodata values and the nodata value is set, just the function run
 with it.  This assumes that the creator/maintainer of the raster knows
 what they're doing so the function goes with what it is given.

 There are no speed improvements for the "hasnodata" flag, just a filtering
