-    /- TODO: fix the following hack.
-       We need to use the following hack because the equation compiler generates auxiliary
-       definitions that are compiled before we even finish the elaboration of the current command.
-       So, if the current command is a `@[specialize] def foo ...`, we must set the attribute `[specialize]`
-       before we start elaboration, otherwise when we compile the auxiliary definitions we will not be
-       able to test whether `@[specialize]` has been set or not.
-       In the new equation compiler we should pass all attributes and allow it to apply them to auxiliary definitions.
-       In the current implementation, we workaround this issue by using functions such as `hasSpecializeAttrAux`.
