| Mar 1, 2014 at 16:21 | comment | added | Oleksandr R. | For the record, I strongly feel that this answer is wrong and misleading in this context, i.e. I fully agree with @halirutan's reasoning. I don't really want to downvote you, because you're right that this is what the documentation claims. But I don't want people to be misled either. | |

Faysal, do you know any examples where adding a third argument to Compile has any effect? Would you consider updating your answer? I feel there should probably be a separate Q&A about this, but I was curious if you knew more.

But the simple example Compile[{}, Module[{y}, y], {{y, _Real, 1}}] fails. Indeed, it seems this type specification at the end is completely ignored and your example only works because of the y={} and because you chose type Real. Try this Compile[{}, Module[{y = {}}, AppendTo[y, 1]], {{y, _Integer, 1}}] and you see, that the type is {Real} although I specified Integer and appended an integer.

I would be surprised that you could have a type related to bags, the only official ones are Integer, Real, Complex, and True | False. In such Mathematica experiments I don't know anything better then try and fail ... but never fail to try ! | |

+1 Although I new this, I never got this running with the declaration of local variables. I didn't know that you have to put y={} together with the type specification. How would I use this to define a Bag of integers, or a Bag of Bags of integers? I would have to know the true internal structure of the pattern or not?
