Well, if you add a space after MD5 ;-).

But that's not the whole thing. From the manpage:

=item qw/STRING/

Returns a list of the words extracted out of STRING, using embedded
whitespace as the word delimiters.  It is exactly equivalent to

    split(' ', q/STRING/);

Some frequently seen examples:

    use POSIX qw( setlocale localeconv )
    @EXPORT = qw( foo bar baz );

A common mistake is to try to separate the words with comma or to put
comments into a multi-line qw-string.  For this reason the C<-w>
switch produce warnings if the STRING contains the "," or the "#"
character.

So, there is a difference, although small.
