What does the -betterC switch in dmd do?

The description in dmd help says: omit generating some runtime information and helper functions. What runtime information are we talking about here? My understanding is that it's basically an experimental feature but when (if) completed what subset of the language would still be usable?

Looks like a bug in the compiler.

or with ~ operator: import std.stdio; [...] Did anyone check that the last loop isn't optimized out? Could also be improved further if you make the function take an output range and reuse one appender for every call, but that might be to far off the original perl solution.
