Use explicit variable name over _

_ is generally used and intented for ignoring options. It allows for
having multiple _ parameters for example. The behavior of this is also

value nil, on 1.9 it works somewhat like a regular name.

To avoid all this confusion, this commit changes it to use a regular
name.
