Hi all,

echo "foobar"["foo"][0];
"foobar"["foo"] - Why not "undefined index"?
Exactly. The index/key "foo" does not really exist in the string
"foobar" because a string is more an indexed array of characters than a
combination of substrings (as the key "foo" could suggest).
"foobar"[3] has a well-defined meaning, but "foobar"["foo"] sounds
strange for me :-). Which semantics do you attached to this syntax?
Cheers.
