Ada is not C/C++, if the assignment operator is available in a type  =

interface, that means it is safe to use. When the assignment operator  =

would not be safe to use and/or would cost too much to the implementatio=
n  =

to be made available safely, then Ada has well know way to exclude it fr=
om  =

the interface: =E2=80=9Climited type=E2=80=9D.

So, yes, if =E2=80=9C:=3D=E2=80=9D is available in the interface, that m=
eans it's not a hack  =

to use it.
