Re: Any caveats in using unpack to right-trim? Why isn't it advertised more?

This was even faster than unpack:

    chomp => sub { 
        my @ret = @a;
        local $/ = ' '; 1 while chomp @ret;
        local $/ = "\n"; 1 while chomp @ret;
        \@ret;
    },

Not nearly equivalent. `\s` matches much more than two characters. And this doesn't even handle the two characters it attempts to handle properly, since it doesn't trim `<SP><LF><SP><LF>`. But it does show that an XS solution that starts at the tail and works in-place would be fastest. This brings up my earlier comment, why doesn't builtin offer this???	[reply] [d/l] [select]
