Try replacing the space character in your match with "\s*". The '*' says to match a whitespace character 0 or more times.

    That would also match words of more than 20 chars "splited", making \s* = "".

    If I had to keep this limitation I would do:

    my @a = grep { /^.{1,20}$/ } split " ", $string
