There are some tricks.  Here's one.

print "3.4*5.6 = @{[3.4*5.6]}\n";

It's not voodoo, so if you don't know what it means it's worth your time
to work your way through it and understand it.  This can be a handy
method for inserting things in the middle of a string, particularly with
big bulky delimiters like here-docs.
