more concise expression for "xxx".to_string()

[electricface]

I think this expression "xxx".to_string() is cumbersome, This @"xxx" can be more concise

@"a line" Equivalent to
"a line".to_string()

[Thiez]

If you really find yourself doing .to_string() a lot, try the following:

macro_rules!s( ( $e:expr ) => ( ($e).to_string() ) )
s!("a line")

[electricface]

like Objective-C 's NSString

[pnkfelix]

there are lots of ways to make a method call more concise. @Thiez already gave one approach (via a macro); but even just a top-level function would suffice (depending on what your input tends to be; if necessary you can define your own trait to overload the function):

fn s<S:StrAllocating>(s: S) -> String { s.to_string() }
s("a line")

1. This use case does not seem worth adding special special syntax to the language.
2. More importantly: language changes need to be proposed via the Rust RFC process: https://github.com/rust-lang/rfcs/

So, I am closing this bug. If you want to suggest your change again, please follow the procedure at the RFC site linked above.
