I’d like to check if a type has `iterate` defined. Of course, `iterate` needs two methods – `iterate(::T)` and `iterate(::T, state)`.
```julia
julia> hasmethod(iterate, (Vector{Int}, Any))
true
julia> hasmethod(iterate, (Tuple{Int}, Any))
false # huh?
julia> hasmethod(iterate, (Tuple{Int}, Int))
true # Oooh...
```
I want to know if there is a two-argument method for `iterate` where the first argument is of some type `T`, but I don’t care what the second type is. I know that I could call `methods(iterate)` and then filter the returned list, but is there some way for me to called `hasmethod(iterate, (Tuple{Int}, *))`?

I think `methods` can be used here:
```julia
methodlist = methods(iterate, (Tuple{Int}, Any))
isempty(methodlist) # false
```

Ah! Brilliant!
