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.

And although readline() yields a String, if you are asking for, say, a Int
or a Float64 value, you can add a second version of `input`:
```
typealias ParseableNumber Union{Float64, Float32, Signed, Unsigned, Bool}
"""
`input{T<:ParseableNumber}(::Type{T}, prompt::String="")::T`
Read an int
"""
`input(prompt::String="")::String`
Read a string from STDIN. The trailing newline is stripped.
The prompt string, if given, is printed to standard output without a
trailing newline before reading input.
"""
function input(prompt::String = "")::String
print(prompt)
return chomp(r
it will be read as a string so you can skip the quotes..
to remove the ballast (single trailing newline from a string) use "chomp"
function
julia> user_input = chomp(readline());
asd
julia> user_input
"asd"

Okay, I accidentally figured the answer for the P.S. by myself.
