+Call a lambda code block with the given arguments. Since the parameters of the lambda
+are local to the lambda's scope, this can be used to create private sections
+of logic in a class so that the variables are not visible outside of the
+class.
+
+Example:
+
+     # notices the array [1, 2, 'foo']
+     with(1, 2, 'foo') |$x, $y, $z| { notice [$x, $y, $z] }
+
+- since 3.7.0
+- note requires future parser
