Some other options: using a common struct member for the common 
cases, and rotating the struct so that you have a 
struct-of-arrays (SoA) instead of an array of structs. Whether 
these are wins depends on what you're doing exactly. If the 
variants have very different fields, SoA stops making sense fast. 
But to add 10 all the ages you would have a function that 
modifies an int[]
