It ought to be noted that the alternative syntax is used essentially for =
strings, not for arrays proper. In fact, I expect that it is used almost =
exclusively for strings.

That means, most probably: ~2.2k uses of alternative syntax for direct =
byte access in strings among 888.3k for byte access in strings AND =
direct element access in arrays.
