[julia-users] Can't declare variable of specific type

[Pranit Bauva]

hey everyone!

I tried defining variables of particular Type in this script. They don't 
work in the "normal mode" but they run in functions properly. To explain 
the problem, here is a code snippet from a file "type_test.jl" which I 
invoked by typing "julia type_test.jl" in the terminal.

function foo()
    a::Int8 = 10
    b::Int8 = 20
    a + b
end

foo()
x::Int8 = 10
y::Int8 = 20
x + y

There shows an error that x is not defined. Can please someone explain this 
kind of behavior ?
