Hello,

Several times I faced with next problem: I have "@safe" routine with few calls to @system functions inside: OS calls (recv, send, kqueue) os some phobos unsafe functions like assumeUnique. I'd like not to wrap these @system functions in @trusted wrappers, but somehow mark these calls @trusted inline.

In ideal case this should look like

import std.exception;

void main() @safe
{
    ubyte[] a;
    @trusted {
        auto b = assumeUnique(a);
    };
}

But the closest variant is

import std.exception;

void main() @safe
{
    ubyte[] a;
    delegate void() @trusted {
        auto b = assumeUnique(a);
    }();
}

Which looks a bit verbose.

How do you solve this problem?

Thanks!

ubyte[] a;
auto b = (() @trusted => assumeUnique(a))();
