|Here is an easier way:
|$_ = <<'EOL';
|   all text from here to that string above in single quotes goes into $_
|   including the newlines.
|   next line intentionally left blank
|
|   EOL #and this because its not on a line by itself
|EOL
|@lines = grep(!undef, split(/\n/,$_));
|print join("\n", @lines),"\n";

Not quite. I don't think split will ever produce an undefined array
element. What it can produce is an empty string as an element, so:

@lines = grep !/^$/, split /\n/;
or
@lines = grep $_ ne '', split /\n/;

will split $_ into lines and remove any blank lines.

Note that if you just want to remove *trailing* blank lines, split alone
already does that.
