You can put whatever code you want between various when blocks. You can also have more than one default - a default is just a when with a condition that's always true: 
my @test = qw [abc def ghi xyz jkl mno];

for (@test) {
    say "Testing '$_'";
    when (/abc/) {say "    Got 'abc'"; continue}
    say "  After when /abc/";
    when (/def/) {say "    Got 'def'"; next;}
    say "  After when /def/";
    when (/ghi/) {say "    Got 'ghi'";}
    say "  After when /ghi/";
    when (/jkl/) {say "    Got 'jkl'"; last;}
    say "  After when /jkl/";
    default {say "    Default 1"; continue}
    say "  After first default";
    default {say "    Default 2";}
    say "  After second default"
}
continue {
    say "    Continue for '$_'";
}

__END__
Testing 'abc'
    Got 'abc'
  After when /abc/
  After when /def/
  After when /ghi/
  After when /jkl/
    Default 1
  After first default
    Default 2
    Continue for 'abc'
Testing 'def'
  After when /abc/
    Got 'def'
    Continue for 'def'
Testing 'ghi'
  After when /abc/
  After when /def/
    Got 'ghi'
    Continue for 'ghi'
Testing 'xyz'
  After when /abc/
  After when /def/
  After when /ghi/
  After when /jkl/
    Default 1
  After first default
    Default 2
    Continue for 'xyz'
Testing 'jkl'
  After when /abc/
  After when /def/
  After when /ghi/
    Got 'jkl'
