// not_nested_func.d
void bar() {
auto i = 0;
auto j = (function() { return i; })();
}
---
$ dmd not_nested_func.d
not_nested_func.d(3): Error: function not_nested_func.bar is a nested function
and cannot be accessed from not_nested_func.foo()
Compare:
---
// not_called.d
void bar() {
auto i = 0;
auto fn = function() { return i; };
}
---
$ dmd not_nested_func.d
not_nested_func.d(3): Error: cannot match function literal to delegate type
'int delegate() pure nothrow @nogc @safe
Here, the error message is confusing, but I at least get a hint that using
'delegate' in place of 'function' might help.
Tested on 2.069.2 and 2.069.0.
