[boost] [assign] typo

Dear Thorsten, It was good to meet you finally last week. I'm reading through the assign docs and there seem to be some misplaced parentheses in the definition of names2 in the preformatted section following the heading "Function list_of()". I think it should say const stack<string> names2 = list_of( "Mr. Foo", "Mr. Bar", "Mrs. FooBar" ).to_adapter(); Best Regards, Jonathan
