Jonathan M Davis:
Local Variables
It is an error to use a local variable without first assigning
it a value.
...
There's no way that this is ever going to be the case. There
are cases where
you can't use a variable's initial value. For example,
T var;
if(cond)
{
//do a bunch of stuff
var = something;
}
else
vare = somethingElse;
I think "use a local variable" doesn't mean "assign it
immediately", it means essentially "reading it before writing
it". So that code is correct.
This could done, but it's definitely _not_ a warning or error
right now. It's
also not ever going to be an error AFAIK, so I'd definitely
vote to remove it from the docs.
I think in Go unused local variables are an error.
If you go here and you try to add "x := 1" inside the main you
receive an error, not a warning:
http://golang.org/#
And I think today Go programmers survive well enough to such
strictness.
