Symbols, just like Keywords, implement IFn for invoke() of one argument (a map)
with an optional second argument (a default value). For example('mysym
my-hash-map :none) means the same as (get my-hash-map 'mysym :none).
So ('+ 3 5) means "Look up '+ in 3, returning what you find, or 5 if you
can't find it.
