You can use the trick mentioned in 'perldoc -q string' "How do I expand
function calls in a string?", referencing, then dereferencing an array, but
it is ugly [...]
What makes you say it "is" ugly?
To me it is just another useful language feature.
But it needs plenty of space. :)
I use $" in here-docs as well:
perl -wle'
my @id = 1..5;
my $sql = do {
local $" = q{,}; #"
<<"SQL";
SELECT
id
, name
FROM
things
WHERE
id IN (@id)
SQL
};
print $sql;
'
For those that are not familiar with C<$">,
change it in the above code to for example qq{\n,\t}
and see the difference in the output.
