My justification for rewriting OAuth.jl's oauth_serialize_url_parameters

rewrite_oauth_serialize_url_parameters.jl

function method_a(options)
    parameterstring = ""
    keyssorted = sort!(collect(keys(options)))
    for key in keyssorted
        parameterstring *= "$key=$(options["$key"])&"
    end
    chop(parameterstring)
end

function method_b(options)
    join(
        ["$key=$(options[key])" for key in sort!(collect(keys(options)))], 
        "&"
    )
end

params = Dict([randstring(10) => randstring(40) for _ in 1:10])

# Warm up...
method_a(params)
method_b(params)

@assert method_a(params) == method_b(params)

sleep(1)  # To semi-ensure JIT is done.

@time method_a(params)
@time method_b(params);
