Beside filters there are also so called "tests" available. Tests can be used to test a variable
against a common expression. To test a variable or expression you add is plus the name of the
test after the variable. For example to find out if a variable is defined you can do name is
defined which will then return true or false depending on if name is defined.
Tests can accept arguments too. If the test only takes one argument you can leave out the
parentheses to group them. For example the following two expressions do the same:
{% if loop.index is divisibleby 3 %}
{% if loop.index is divisibleby(3) %}
