Because some of the pair literal syntaxes (:enable, :enable(1), enable
=> 1, but for example not "enable" => 1) are also used for named
arguments, and sub flat doesn't want a named argument.

Putting the parens around it force it not be a named argument.

ok .. to make sure i understand: if flat had a :enable named parameter,
the way to use it to get

{:enable{True}, :ok }

with the named parameter to False, would it be 

my %x = :ok;
flat ( enable => True, %x ) :!enable;

hello Moritz,

i tried :p but the thing is i was searching for something straight as
the perl5 

my %y = (%x, qw( enable 1 ));

si i really loved  

my %x = < login jdoe first john last doe >;
my %y = ( :enable, %x< login first >:p);  

to work. thanks for showing me this working code. 

actually, it rises a new question to me: why the parenthesis around
flat are mandatory?

my %x = < login jdoe first john last doe >;
my %y = flat (:enable, %x< login first >:p);

is ok but 

my %x = < login jdoe first john last doe >;
my %y = flat :enable, %x< login first >:p;

give me
