Unfortunately slicing by code units is probably the most important
safety issue with the current implementation: As was mentioned in the
other thread:

size_t index = str.countUntil('a');
auto slice = str[0..index];

This can be a safety and security issue. (I realize that this would
break lots of code so I'm not sure if we should/can fix it. But I think
this was the most important problem mentioned in the other thread.)
