Nope, you can only hyper operators, not terms. Incidentally, just like mathematically (albeit slightly loosely) an element of a set can be thought of as a function from any singleton, would it be possible for Perl 6 to provide a fast (under the syntactical point of view) way to promote a term to a function returning it?

What's wrong with the perl 5:

return sub { $x }; # the sub{$x} is the construct
}

I am a little confused if the following is valid perl6:
our xsub = { $x };
I believe that would work and install this function in the package global
symbol table because xsub is the reference to the function xsub.
If you wanted to get a function for each element in an array @a, I suppose
you can say:
sub makefunc($x){{$x}}
@funcarray = @a.makefunc;
And that can also be shortened to:
@funcarray = @a{my $x=$^x;{$x}};

I certainly hope not.
Quoting the delimiter is needed, by the way.
How is 'END' disambiguated from 'qw' list, anyway?
Seeing the « in the context of a here-doc made me think can you do a
» here-doc?
So, something like :
@text = »END;
text1
END
text2
END
text3
END
text4
END
for @text { ...}
The hard question about this is: how do you know when you've hit the
last END? especially if the text you're loading looks like Perl code, or
if you have different END later in your code?
btw, should it be », «, or »«?

I think you have a really good place for a split there. Then there's
no ambiguity about which is the internal separator and which is the
final delimiter.
: btw, should it be », «, or »«?
Er, can I pick D?
