IMO the parametric method with multiple dispatch is more Julian.
or, the more specific
function read_integer(prompt::String="")::Int
print(prompt)
str = chomp(readline())
return parse(Int, str)
end

with Yichao's help,
typealias ParseableNumber Union{Float64, Float32, Signed, Unsigned, Bool}

`input{T<:ParseableNumber}(::Type{T}, prompt::String="")::T`
Read an integer or a floating point value from STDIN.
The prompt string, if given, is printed to standard output without a
trail
Thank you, that is helpful.
