What are some quirks / surprises using .mm files in Objective-C?

Question

I want to use some C ++ STL collections in my Objective-C iPhone app. This seems to be possible by providing the files with the extension ".mm". What are some of the quirks / surprises associated with this?

I want to use basic containers that I am familiar with (vector, queue, set, ...)

Hurrah!
