that is very slow and clunky. perl could slurp the file for you if
you set $/ to undef. or better yet, use File::Slurp to do it
Yes, definitely better to set $/ to undef.
I'm still trying to get a handle on the libraries at my disposal --
There's so much in CPAN it's hard to know where to start. Is it
equivalently efficient to use IO::All or IO::Simple, or is File::Slurp
truly the best for this purpose?
I ask because I played with IO:All to read files, enjoyed the simple,
intuitive syntax " my $filecontents < io('filename'); ", but (perhaps
naively) assumed the native "open my $fh" to be faster since it doesn't
require a "use" to load a library.

why are you using m//? the m isn't needed if you use // for
delimiters
Yeah, I know, I don't need it... being verbose (sometimes) keeps a
newbie like me from making silly mistakes :-)
My initial experimentation with Perl has been mostly in a line-by-line
mind-set because I have a tendency to write scripts that are used like:
some-unix-command | perl -wne 'do some processing' > myresults.txt
I'm trying to expand my horizons, thanks for help,
Brian
