how do you interpoplate against units in a here-doc?

[~greg]

problem is something like this:

var $WIDTH = 10;
print OUT <<__;
....
width: $WIDTHpx;
....
__

to print
....
width: 10px
....


What can be insert between the "$WIDTH" and the "px to make this work?

(don't want to break up the here-doc.

Thought of using $X = "" but that obviously doesn't work.
If there is a special variable (like $_)
that's == "", that might work.)
