It's concise and has a very specific meaning. If one is working 
with mathematical objects and set up correctly then it can be 
more easily interpreted because it is `inline` with standard 
mathematical syntax.

It's the same reason mathematicians prefer ∩ over intersect. You 
would prefer it too if you got used to it. The whole point of 
symbols is to simplify, ∩ is more simple than intersect as the 
first requires 1 symbol and the second requires 8 symbols.
