Given this, I think the general argument goes roughly like the following:In general it seems possible to identify iterators/generators as needed for this purpose: - someone actually implemented this feature already (see#5863) - there is ``type.GeneratorType`` and ``collections.abc.Iterator`` for ``isinstance(...)`` check - numpy can destinguish them already from all other types which get well translated into a numpy array
which in total, at least for me at this stage, speaks in favour of mergingPROS (effect maybe 10% of numpy user or more): - more intuitive overall behaviour, array(...) = array(list(...)) roughly - python3 compatibility (see e.g. #5951) - compatibility with analog ``__builtin__`` functions (see e.g. #5756) - all the above make numpy easier to use in an interactive style (e.g. ipython --pylab) (computation not that important, however coding time well) CONS (effect less than 0.1% numpy user I would guess): - might break existing code
