Maximum value for Julia integer types

General Usage
1

Julia Integer types have a minimum and maximum value.
When calculations go beyond those boundaries, results are ‘incorrect’.

for i in Int8[5, 10, 15, 20]
    println(i, " -> ", i^2)
end

Result:

5 -> 25
10 -> 100
15 -> -31
20 -> -112

Question:

Is there an efficient way in Julia to raise an exception when this occurs?
This to prevent this from happening without noticing.

Maybe there are better solutions than raising an exception.
