I would like to discourage you from passing symbols as an array index but I
guess you gonna do it anyway...
So if you really want it, here it is:
setindex!(p::Population, value, field::Symbol, index...) = p.individuals[
index...].(field) = value
getindex(p::Population, field::Symbol, index...) = p.individuals[index...].(
field)
Usage
population[:infected, 1]
population[:infected, 1] = false
