This isn't valid code. The goroutine is declared with a w arg, but it
is not called with the parameter.
Assuming you intended to pass the w declared outside the for loop: is
it possible that the whole thing is inside another for-loop, and w is
the loop variable?
for _,w:=range ... {
// your code here
}
If that's the case, just add a w:=w at the top of the for loop:
for _,w:=range ... {
w:=w
// your code here
}
If that's not the case, maybe posting code that compiles might help.
