No. Code has to understand that there is a difference between:
const char *
char *
char []

The first is a pointer to a character constant, the second to a character
[field] and the third is a field. E.g. if you want to define a modificable
character constant,
char *foo = "bar";
is wrong. That's a pointer to "bar", the correct syntax is
char foo[] = "bar"

We still want to be very careful about the qualifiers used in interfaces,
but we have to live with the few cases we can't change them.
