i would say to just use a temporary scalar variable. there is no shame
in doing this and it is simpler than using the Interpolation module
which is doing tied things and calling eval (which is dangerous).
When I dont want to use a temp var, I usually do like this:
print << "EOF";
foo @{[scala

rray, but

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{,}; #"

Funny that the perldoc uses the exact function I wanted to use:)

Inside a here doc, how can I force an expression to be evaluated
such as localtime:
print <<"END";
`localtime time`
Foo
Bar
END
I know I can simply create the var before,
my $var = localtime time;
But just curious how to evaluate expressions inside this...
Thanks!
