 Flytekit offers a mechanism for chaining Flyte entities using the `>>` operator.
 This is particularly valuable when chaining tasks and subworkflows without the need for data flow between the entities.

 ## Tasks
 
 Let's establish a sequence where `t1()` occurs after `t0()`, and `t2()` follows `t1()`.
