It could be nice to have a syntax like lambdas for small 
struct/class methods:
https://issues.dlang.org/show_bug.cgi?id=7176

struct Foo {
     int bar(int x) pure { return x * x; }
}

Becomes something like::

struct Foo {
     int bar = (int x) pure => x * x;
}

Ada2012 and C#6 have something like that (with a different 
syntax).

Unwanted access of global variables is a common source of 
troubles in my code. Time ago I suggested an optional @outer() 
function annotation:
