it didn;t work
Please elaborate. It seems to work for me when I run your 2nd code example. Here is the output I get: 
$r = (defined $ENV{HOST} ? $ENV{HOST} : 'sqlhost')

What do you expect the output to be? First, you print the statement verbatim, then you print the eval'd statement. I do not have the HOST variable set.
