Embedding tasks in the data structure is usually not a good idea. For
one thing, tasks are "limited" types, so the Student record type also
becomes "limited", and you can no longer move such record objects from
here to there with assignment statements. For another thing, each task
needs its own stack and control structures, which can consume
significant amounts of memory. Finally, the execution state of a task
can be complex and is private to the task and is not directly visible or
controllable from "outside", as the values of other kinds of
data-structure components are.

Can you explain what you want to accomplish here? What is this task
supposed to do, and why must it be embedded in a Student record?
