Struggling with collection types

Hi,

The following works:

function Price(components::Dict{String, <:Real}; precision::Integer = 2)
    price = Price(precision = precision)

    for entry in keys(components)
        price.components[entry] = round(components[entry], digits = precision)
    end

    return price
end

Price(components::AbstractVector{<:Pair{String, <:Real}}; precision::Integer = 2) = Price(Dict{String, Float64}(components), precision = precision)

You used key instead of entry and your AbstractVector needs to be of <:Pairs.
