I vote for this. `$_` represents an unnamed scalar, it refers to
the implicit topic of a section of code, whereas all other
variables are explicit names of particular values.

The `local $PWD = '/some/where'` interface of File::pushd makes
intuitive sense: `$PWD` is inherently special and I am locally
assigning this special kind of a variable a new value. You can
imagine the same thing for a variety of other kinds of variables,
eg. if I saw `local $UMASK = '0007'` is just as natural.*Only*
for `local $_` does this intuitive expectation differ because
`$_` is not the name for one particular special thing.
