I bet in 99% of cases using such structure is a nonsense overhead, and in 85% the code relaying on it can be written without a single heap allocation.


One man's nonsense overhead is another's labour-saving modern convenience ;)

(I like to write my code without heap allocations, but when you need an array of arrays of strings, indexed by another string, it doesn't half get a bit annoying to code up.)
