I mean I don't want to use the other packages via R-level, but directly

But it seems to me, that when later the names-result will
be correctly set to 0, 1 and 2, then such optimisations,

But if they do not substitute all these deprecated functions,
then either porting the stand-alone-code to R is made
much effort, or the deprecated functions might just stay inside.
Do you see what I mean?

At the moment R rather deprecates in-place modification by default

But it's not true, that R in general copies arguments.
But this seems to be true for the .C interface.

The other problem, someone mentioned, was *changing* the contents

But the namespace-name / variable-name as "references" to the matrix

If I here "type safe" I rather would think about OCaml

Also, LISP has so many "("'s and ")"'s,

If you compile/link the code together,
