Hope this isn't a stupid question, but how would you access this function if it did work?<BR>
Would it be fun("asdf")?<BR></BLOCKQUOTE><DIV><BR>Yes, that's what I had in mind. Basically, just using it as any other auto inner function. <BR><BR>void main()<BR>{<BR>auto fun(string s) { return s;}<BR>auto s = fun("abc");<BR>

Is this just shorthand for:<BR>
auto fun = function(string s) {return s;};</BLOCKQUOTE><DIV><BR>That'd be about the same, yes. Fact is, I don't really _need_ this, I was just astonished to be bitten by this.<BR>Why can I do<BR>
<BR>void main()<BR>{<BR> string foo(string s) { return s;}<BR>}<BR><BR>and not<BR><BR>void main()<BR>{<BR> auto foo(string s) { return s;}<BR>} <BR><BR>?<BR><BR>***<BR><BR>OK, I tested it some more, and it seems you cannot define auto function inside any other function. So auto function cannot be inner functions. I'm quite astonished I never did that when using D, but OK.<BR>
