How do I use a constant in a heredoc?

$sample = <<<sample_code

SOME_CONSTANT

sample_code;

echo $sample;

The constant in that case is just showing it's "name".

As far as I know you cannot. Heredoc is not as useful as it looks :)

Anyway, there's a user note that suggests a dirty trick:

Thanks, the "dirty" trick is a bit of an understatement!
