When an exception causes a stack trace to be printed on Linux, only top-level
functions are shown.  If nested functions are to become idiomatic D style (I
use them a ton) then nested functions should be printed as well.  Test case:

void main() {
    doIt();
}

void doIt() {
    void nested() {
         throw new Exception("Test.");
    }

    nested();
}

Stack trace:

object.Exception: Test.
----------------
./test(void test.doIt()) [0x8057cf9]
./test(_Dmain+0x8) [0x8057ccc]
./test(extern (C) int rt.dmain2.main(int, char**)) [0x805a456]
./test(extern (C) int rt.dmain2.main(int, char**)) [0x805a3b0]
./test(extern (C) int rt.dmain2.main(int, char**)) [0x805a49a]
./test(extern (C) int rt.dmain2.main(int, char**)) [0x805a3b0]
./test(main+0x96) [0x805a356]
/lib/tls/libc.so.6(__libc_start_main+0xd3) [0x8c3e93]
./test [0x8057c21]
