[FWP] Small "fun" with Double quote interpolation

[Vicki Brown <vlb@cfcl.com>]

Another little one

I tend to wrap print statements in double quotes,

    print "the foo variable contains $foo\n";

But I was recently tripped up when I tried

    use Boulder::Blast;

    # ... intervening code removed

    $blast = Boulder::Blast->parse($outputfile);

    print "$blast->Blast_db\n";

Serves me right to type on autopilot. Chris has been telling me to 
break this habit...

Wanna guess? (Spoiler below)











     Stone=HASH(0x1dba98)->Blast_db
