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:
sub mysub($x) { return sub { $x }; # the sub{$x} is the construct }
or the perl6
$xsub = { $x };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}};--abhijit
