in it's self this is a 'neutral' - probably a hold over
from doing things cautiously in /bin/sh and simply hauled
into doing that defensive coding in perl.
As you may have noted from earlier scoping questions think of the case
my $var = "me";
my $var2 = "${var}2";
at which point $var2 has the string 'me2'
without the curlies and quotes it would have the
bare word problem or worse... be simply self referential:
my $var2 = $var2 ;
Some coders are MORE PARANOID than others....
