Dango would be more appropriate for a dequeue, as it's not random access - you can only remove pieces from either end of the skewer. The bento box makes more sense for an array, because you can pick from any compartment.
Pancakes for a stack, popcorn for a heap, burrito for a monad.
So... just to be clear... you're serious...? I smell a clever troll.
Ah yes, because nothing says “data structure consisting of a contiguous block of memory broken into uniformly sized chunks so elements can be cheaply accessed by index” like a little picture of rice dumplings on a stick. Much better than just using the accepted technical term “array”.
Personally I prefer the abbreviation arrr, or sometimes yarr. Lets anyone reading the code feel like they just downed a pitcher of grog.
Emojis combine the best of both worlds. Like the letters used in math they are easy to parse and it's really easy to find other occurrences of the same var when the name is an apple . But like the more verbose names in programming languages they can carry meaning. Eg I use the dango emoji for arrays and the monitor emoji for window instances.
