Thanks; I have seen this and other proposals, but none of them address
the problem that most people don’t expect a crash when using
"..*most* people don’t expect.." could you prove this please? Perhaps you
want to say *many* people. Probably. But the same many people expect this.
Especially if they know a little of C language or other language that don't
allow to use wrong indexes for arrays.
Also, why they don't expect this when writing in Swift? This behavior
described in help/documentation/tutorial for Swift, this is how Swift works
with arrays.
subscripting – except for Erica’s excellent suggestion to make subscript
throw, which would also require considerable changes to existing code.
I'm not sure about this idea. Still - if you'll use wrong index your
program will crash by thrown exception. Or I don't understand the suggestion.
