It makes it clear the operation you are dealing with is not array access
and is not bound by its rules, but another operation with (possibly)
different rules which you need to learn.

That would solve the situation where we imply that strings are like
arrays by using same syntax only to break that promise with many
operations.

That would be much harder to do and largely pointless unless we make
string offsets be real zvals. Which I strongly recommend against - we
have enough trouble with pointer-like nature of references, one more
pointer-like time would produce huge amount of trouble.
