While you can often circumvent the usage of `break` and `continue` in twig, it sometimes leads to additional nesting and more complicated code. Just one `break` or `continue` can clarify behavior and intent in these instances. Yet I would advise to use `break` and `continue` sparingly.

Adds a strict true/false test, so expressions become a bit more readable:

Adds tests known from PHP, so you can test a value for being:

99+
- an array (like `is_array`)
100+
- a boolean (like `is_bool`)
101+
- a callable (like `is_callable`)
102+
- a float (like `is_float`)
103+
- an integer (like `is_int`)
104+
- an object (like `is_object`)
105+
- a scalar (integer, float, string or boolean, like `is_scalar`)
106+
- a string (like `is_string`)
107+
- true (like `=== true`)
108+
- false (like `=== false`)
109+
110+
It uses the mentioned PHP functions / comparisons internally, so you have the same behavior as in PHP.
