You're having a hard time coping with the fact that $_ is an alias to the
values in the list you're mapping over, not a copy.

Not necessarily prettier:
@new = map {m/(.*)(?:jpg|gif)$/i?"$1html":$_ } @old;

I, too, am interested in this syntax. I had to do the same juggling in order to "map"
the values without affecting the original array -- and would prefer cleaner syntax if
it's possible. Thx! Karl

Hi Eric,
if you want a more pretty way, (if a touch slower) try:
my @new_names = @old_names;
foreach (@new_names) { s/\.(jpg|gif)/\.html;i ; }
I personally don't like map as I came to PERL from C, but if you want to
use it instead...
my @new_names = @old_names;
map s/\.(jpg|gif)/\.html/i, @new
