Golang error (Slice of unaddressable value)

This is a creation in Article, where the information may have evolved or changed.

The process of converting the generated MD5 to string using Golang has the following compilation error:

Error Resolution:

It is important to note that the Func Sum (data []byte) [Size]byte] Returns the result of the array instead of the slice (slice).

The following example shows that the compiler error line is because [3]int{1,2,3} is not assigned to any variable, the compiler does not know its address, so compiling to [:] will cause an error. The workaround is to assign [3]int{1,2,3} to a variable and then slice the variable.
