Someone on alt.perl asked:
What is elegant way of convert string like "--param1 blabla --param2 bla bla blo" Into assoc array $a{"param1"} == blabla and $a{"param2"}== "bla bla blo" ? Param values never starts with "--".
Here's my reply.
my $string = "--param1 blabla --param2 bla bla blo";
my %newhash = $string =~ /--(\w+)\s+(.*?(?=\s*$|\s*--))/g;
for (sort keys %newhash) {
  print "$_ = <$newhash{$_}>\n";
}
