--- Comment #1 from kinke <kinke at gmx.net> ---
I'm not sure this should work - `extern(<lang>)` doesn't affect the mangling of
nested functions either, only ABI/calling convention. The reason is simple,
nested functions are D only, and the D mangling makes sure there are no
duplicates/conflicts (as it includes the parent function(s)).

The IMO more intuitive workaround is a freestanding function. Exposing a nested
D function for consumption from C[++] is probably not very common; I guess the
main usage would be consuming an external function from D, and declaring it as
nested function in D for locality.
