+Reference as array: `$@`.
+Reference as string: `$*`.
+
+Let's say we want to open a file in our favorite editor through a script, prefixing the filename with something such as a date.
+If we were to use `hx "$(date) $@"`, where we reference the arguments as an array, it'd open more than one file - one for the date and one for each argument.
+We must use `$*` so that our invocation becomes `hx "$(date) $*"`. This would open a single file with the name being the combination of our arguments prefixed by date. \ No newline at end of file
