I made a dictionary to store some inputs to a function, see below

```julia
    data = Dict()
    data["total_time"] = 0.3
    data["time"] = 0.
    data["dt"] = 1e-3
   function f(data)
        Tf = Float64(data["total_time"])
	dtime = Float64(data["dt"] )        
	t = Float64(data["time"])      
	fric = Float64(data["friction"])
   end

```

Then, I do: @code\_warntype(f), and saw this:  
t::Any  
Tf::Any  
fric::Any

My question is why?
