Iteration over stl containers (or indeed any class with ``begin()`` and
``end()`` methods returning an object supporting incrementing, dereferencing,
and comparison) is supported via the ``for .. in`` syntax (including in list
comprehensions). For example, one can write::
comprehensions). For example, one can write:
cdef vector[int] v = ...
for value in v:
f(value)
return [x*x for x in v if x % 2 == 0]

If the loop target variable is unspecified, an assignment from type
``*container.begin()`` is used for :ref:`type inference <compiler-directives>`.
