Description

It can bite you when for example you are coloring rows in your table in some pattern. After refresh you may get different coloring (if you use the sample compiled template, which is not true for default django template processing).

from django.template import Context, Template
t = Template("{% cycle 1 2 3 %}")
t.render(Context())

u'1'

t.render(Context())

u'2'

t.render(Context())

u'3'

t.render(Context())

u'1'
