I can understand that thinking, but I don't think it's correct. It's my understanding that Perl will treat a double-quoted string that contains no variables as a single-quoted string. Example: 
perl -MO=Deparse -e 'print "hi"'
print 'hi';
-e syntax OK

Also, the word you were thinking of is "interpolate", not "concatenate". :)

It's all fine and dandy until someone has to look at the code.
