You might even consider always using ${} for ALL variable substitution.

It's a little harder to type but easier to search for (fewer mis-finds,
esp. with small names) and reduces incentive to follow tradition of
using all caps for envars.  It's debatable whether it's easier or harder
to read, but more lower and mixed case probably helps readablity.
