that is always a lousy constraint. seen it too often in some places.

using a var is fine. the main win is perl regexes vs globbing which is
very limited in matching power. globs can keep the prefix dir for you
which is nice. if i ever get the prefix option to read_dir i could even
make it a new function like read_dir_prefix and then the code would be

	my ($file_name) = read_dir_prefix qr/${job_no}XX-.*\.txt/, $from_dir ;

and that reads pretty well and is about as short as you can get. still
cpan but lobby and it could be in core one day! :)
