Groovy: Java má vzdáleného bratrance

Pre referenciu predkladam riesenie v Perle:

#!/usr/bin/perl

$urlArgs = '=Value1&Key2=Value2&Key3=1999-12-02';

%params = map  { +"\l$$_[0]" => "\l$$_[1]" }
          map  { $$_[1] =~ s/^(\d{4})/$1 < 2000 ? 2000 : $1/e; $_ }
          grep { $$_[0] =~ /^\p{IsUpper}/ &&
                 $$_[1] =~ /^(\p{IsUpper}|\d{4}(-\d\d){2}$)/ }
          map  { [ split /=/, $_ ] }
          split '&', $urlArgs;

print "$params{key3}\n";

Opat linearne pridanie zopar prikazov do existujuceho kodu. Standardny Perlovsky text-processing.
