Currently it is, due to argument modes (map takes a function that expects its argument by-reference, str::split takes it by value). We're hopeful that we've found a way to get rid of this restriction, once the region work is more complete, but it might take a while before all that is implemented. _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
