In GOLANG, Is there a way to make a variable's scope local to a file within a package? In my case, there are 2 files ex1.go and ex02.go. ex01.go defines a global variable
var wg sync.WaitGroup
which is used across functions in that file.
In another file ex02.go (which has no relation with ex01.go except that both ex01.go and ex02.go belong to the same class of problems - i.e. concurrency), I can't define a variable for waitGroup as
var wg sync.WaitGroup
I get an error - "variable name is re-declared in this block"
Is there a way to keep the variable names from spilling over to the other files?
