How to get the value of field

In julia i can get a list of fields like so

INPUT:
type Foobar
    foo::Int
    bar::String
end

baz = Foobar(5,"GoodDay")
fieldnames(baz)

OUTPUT:
2-element Array{Symbol,1}:
 :foo
 :bar

But how can access the values of those fields, given the names that I am finding dynamically?

I know one way is to build the expression myself:

fieldvalue(v,fn::Symbol) = eval(Expr(:(.), v, QuoteNode(fn)))

That is kinda scary looking, so I think there is a better way.

Usecase:

INPUT:
function print_structure(v)
    for fn in fieldnames(v)
        println(fn,"\t", fieldvalue(v,fn))
    end   
end
print_structure(baz)

OUTPUT:
foo 5
bar GoodDay
