unable to template 'internal' field of task

[Diaphteiros]

Description

I would like to dynamically hide some tasks, depending on some variable's value. But it seems that the result is always a string - which is rejected by the task's internal field - even if the resulting value is a bool.

err:  cannot unmarshal !!str `{{ eq (...` into bool
