This is similar to bug 10288.

Nested function 'bar' accesses to outer scope variable 'a', so it's inferred as impure. But, 'bar' does not access to variables out of 'foo', so the outer function 'foo' should be still inferred as pure so calling 'bar' does not break its purity.

pure void main()
{
    foo();
}
void foo()()
{
    int[3] a;
    void bar()() { a[1] = 2; }

    bar();
    pragma(msg, typeof(bar!()));    // nothrow @safe void()
}
