  Looks good, apart from the "more human readable" sarcasm. :) Oh and
a few small things:

  'feature' is singular so 'one_' is pretty much redundant here.

  I'd suggest using 'iter_func' or just 'func' as the parameter name
but this is entirely subjective so feel free to ignore this
suggestion. :)

  Since 'cont' is only used once and there is no big line (to not fit
in the 120 cols limit), I suggest not using it here.

  ACK otherwise.
