I see the point, but... this is the same for functions and procedures  =

(except the entry point procedure or function).

I've just checked deeper: compilation_unit includes subunit, which  =

includes separates, which can be a separate task_body (follow links  =

starting at 10.1.1). But, if you follow from compilation_unit to  =

library_unit_declaration, you cannot reach anything like a task (or a  =

protected).

Detailed:

    * subunit may be: separate (parent_unit_name) subprogram_body |  =

package_body | task_body | protected_body
    * library_unit_declaration may be: subprogram_declaration |  =

package_declaration | generic_declaration | generic_instantiation
    * library_unit_body may be: subprogram_body | package_body

So task or protected are compilation_unit... only when separate ? So wha=
t  =

makes it not a compilation_unit when not separate ?

Unless I am missing something else, this seems strange to me.
