In this code, foo and bar are essentially equivalent, but foo is not inferred
to pure.

T foo(T)(T x)
{
    ()  trusted { x += 10; } ();
    return x;
}
T bar(T)(T x)
{
    void lambda()  trusted nothrow { x += 10; }
    lambda();
    return x;
}
 safe pure nothrow void main()
{
    assert(foo(10) == 20);
    // -> Error: pure function 'main' cannot call impure function 'foo'

    assert(bar(10) == 20);
    // -> OK
}
