I was looking through the apache error log for layout tests for some reason, and found 86 instances of:

[Thu May 11 09:06:17.785389 2017] [cgi:error] [pid 30674] [client 127.0.0.1:36073] AH01215: Useless use of a variable in void context at /b/s/w/ir/third_party/WebKit/LayoutTests/http/tests/resources/post-and-verify-hybrid.cgi line 15.


This line:

    @values;

is probably supposed to be

    my @values;


kinuko, it's been a while since you wrote this, but can you take a look?
