This is basically a good idea, since attempts to modify string
literals are non-portable.

-The Committee apparently considered this for the language itself

-and they felt this was too high a burden to place on those using
-a new compiler.

No, the main counterargument was that there is a lot of existing
code that depends on the ability to modify string literals (e.g.
mktemp() on UNIX), so compilers for those clientele would best
preserve that property.
