Misleading compiler hint for wrong keyword constructor syntax

[vektordev]

The following code

struct MyClass{
    pub field:i32,
}

fn main(){
    let myClass = MyClass{field=5};
}

produces the following error message:

error: expected one of `,` or `}`, found `=`

This code errors because "field=5" should be "field:5". The error message leads any good python programmer astray. I think the error message should at least mention the possibility of :.

This probably belongs in A-diagnostics
