The existing intro makes it look like you should use `$<varname>` to refer to a variable. That of course is incorrect, and you should use `$varname`. In my experience using the <> marker around variable names should only be used when there isn't something else explicit to set it off. In this case we have `$`. Below, you can see the <> are also not used, because we have the `[[]]` to set it off. The inconsistency is confusing.
