[Bro-Dev] syntax consistency question

[Gregor Maier]

Yeah, I also discovered that vectors are kinda limited in their
functionality. I think it would be great to have two different data
types in Bro. Possibly both supporting the same.

* array or vector (pretty much like the current vector type):
  + O(1) random element access
  + O(1) (armotized) adding to / removing from *end*
  + O(n) adding to / removing from *beginning*
  + grows (shrinks?) dynamically.

* queue, deque (for FIFOs, stacks, etc)
  + O(n) random element access
  + O(1) adding/removing from *either end*

I understand that internally vectors are really much more similar to tables than sets, but in usage they're more equivalent to an ordered set than a table (in my mind at least).  If we add FIFO-type operations to vectors so that they're easier to work with, they would feel even more like ordered sets.  For example, using a totally made up code snippet...
