Johan Granberg:I think it is an acceptable tradeof that the people that need optimal speed write there code in a more uncompressed formm using manual loops or wathewer. Then the cases not on the criitical path of the program can be written more compactly using a slightly slower but much faster to write style.
In this specific case the compiler must become smarter and able to optimize away the performance loss. Otherwise it's a failed language and a failed compiler. Bye, bearophile

Exactly. Array operations must be optimally fast (faster than a manual loop, in general), or else refuse to compile. They are not syntax sugar.
