I wasn't really making a golf point, just trying to simplify. No need to mess with localized perlvars just for newline.

For golf, you can take out the spaces:

print join$/,<*.$ext>;

If you want really that final newline, we can still cut out two chars from your last one:

print$_.$/for<*.$ext>;
[download]

and of course remove the trailing semicolons :)
