[julia-users] "get" is more eager than I thought

[Adam Kapor]

Is get supposed to evaluate the fallback argument?  I was surprised by this:

julia> dict1 = {1=>1} 
{1=>1} 
julia> dict2 = Dict() 
Dict{Any,Any}() 
julia> get(dict1,1,get!(dict2,1,2)) 
1 
julia> dict2 
{1=>2}

The other method is more what I'd have expected
julia> get(dict1,1) do
       ()->get!(dict2,1,2) 
       end 
1 
julia> dict2 
Dict{Any,Any}()
