Ok. No metaprogramming, though.

I found this:

"The str type in Rust is represented exactly the same way as a vector of bytes 
([u8]), except that it is guaranteed to have a trailing null byte (for 
interoperability with C APIs)."

0 terminated strings are a source of a lot of speed issues in C and C++ code.

and:

"Like vectors, strings are always unique. You can wrap them in a shared box to 
share them. Unlike vectors, there is no mutable variant of strings. They are 
always immutable."

No slicing.
