Research direction

Start by tracing how Transcrypt translates Python for-loops whose iterable is range, then compare the generated JavaScript for range(begin, end, step) with the requested loop form. The issue is done when extra range arguments produce the intended JavaScript loop rather than regular-sequence iteration, with relevant translation checks passing.

Written by the indexing model from the issue text.

Description

STATE: under consideration

If range has extra arguments, it treats for loop like a loop over regular sequence.
It should be fairly trivial to make
for i in range(begin, end, step)
to translate into
for (i=begin; i < end; i += step)
