Description Martin Nowak 2015-05-04 17:17:01 UTC 
cat > enh.d << CODE
struct Foo
{
    deprecated("use foo() instead")
    this();
}
CODE

dmd -c enh

----
Error: constructor enh.Foo.this default constructor for structs only allowed with @disable and no body
----

There is no mean to deprecate default construction of a struct before finally disabling it.
We should enhance the compiler so that the above declaration is valid and using `Foo foo;` would emit a deprecation warning.
