the invocation of s/// is s/SEARCH/REPLACE/modifiers;
where SEARCH is a regex and REPLACE is (in the
absence of the /e modifier) a double-quote interpolated
string (unless the delimiters are ' single quotes).
so the replacement string /9{1,5}/ would be a literal
'9{1,5}' - probably not what is wanted. the '{1,5}' part
has no special meta-meaning when interpolated in a
double-quoted string; it is not some kind of quantifier.
see: 'Regexp Quote-like Operators' in perlop; perlre;
perlrequick.
