Yes, and most well written scripts cleanup after themselves. However,
some scripts don't and more importantly there are times when you can't,
e.g. <break> hit in the middle of your script, or the process of the
user running your script aborts, etc.

But this is not the main benefit of script-local vars, IMHO.  I see
the main benefits: 1) being able to re-scope predefined HP vars, like
DSLINE or HPMSGFENCE, 2) having assurance that the local vars your
script is using do not conflict (meaning overwrite) with other local vars
or job/session vars of the same name, e.g. the ubiquitous var I.
