You might be surprised.
I'm sure plenty of people can find examples where these operators are used, but
many of the major text processing and diagram applications, make only trivial
use of the power of save and restore.
This is of course a generalisation... :-)

My interpreter has managed without for quite a while now.
I've had other comments about it, but very little said about save and restore.

Most interpreters are incomplete because the language is not trivial to implement.
Freely available interpreters (such as mine) are likely to be more incomplete than
those people charge money for (such as Adobe's), for obvious reasons.
