It's a lot easier to read the punctuation in $() than ``,
especially if you have crappy fonts that make ` look like ' or
even like it's not there; books are frequent offenders here.
And, when providing examples for newbies, `` often becomes one
of `' or '' and they get surprised by the results.

When I'm typing at my own private screen, I always use ``; when
I'm providing examples, I tend to use $().
