Conversion from NamedTuples to Dicts not allowed

[lazylavenders]

I was writing a polynomial library and stuck upon a dragon. Why can i not convert between a Dict and a NamedTuple even when they are very similar types?

julia> q = (q="Meow", w="Roar", e="8", r=":q")
(q = "Meow", w = "Roar", e = "8", r = ":q")

julia> Dict(q)
ERROR: ArgumentError: Dict(kv): kv needs to be an iterator of tuples or pairs
Stacktrace:
 [1] Dict(kv::NamedTuple{(:q, :w, :e, :r), NTuple{4, String}})
   @ Base ./dict.jl:132

   @ REPL[2]:1
...

julia> convert(Dict, q)

NamedTuple does not iterate pairs like the other types listed, so you need Dict(pairs(q)) if you want to convert it to a dictionary

[lazylavenders]

But since every time i need to convert from NamedTuple to Dict that i need to use Dict(pairs(q::NamedTuple)) wouldn't it make sense to actually just have Dict(q::NamedTuple)?
Correct me if I'm wrong, and why does NamedTuple not iterate pairs?

Thank you for any help, lav.
