           Summary: auto functions cannot be inner functions
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com

It seems auto function cannot be inner functions:

void foo()
{
    string bar(string s) { return s;} // works
    auto   baz(string s) { return s;} // error!
}

Errors:

main.d|13|found 's' when expecting ')'|
main.d|13|semicolon expected, not ')'|
main.d|13|found ')' instead of statement|

Reading the docs, nothing tells me auto functions cannot be used as inner
function. So either it's a bug or you should update the docs.

While skimming parser.c I noticed that the auto keyword is treated like a
storage specifier, so this one is allowed:

auto void bar() { }

The spec says nothing about this case, but it seems nonsensical.

For newer DMD versions, the error messages seems to have moved a level higher:
»function declaration without return type. (Note that constructors are always
named 'this')«
