I thought #{var} was used within quotes to get the value as otherwise you just get var...

var = "Hello Ruby Talk World"
"I just wanted to say #{var}" -> I just wanted to say Hello Ruby Talk World
"I just wanted to say var" -> I just wanted to say var

or am I missing the point?

To me it's easier to do the above and much cleaner than the following:

print "I just wanted to say " + var + ", love the slippers!"

Or am I just showing my ant roots again...? ${var}

Gem

OK. I'm a bit confused, though. I've been using #{var} for quite a while 
now. I thought it was needed when getting a variable within a block. Is 
it when it's in double quotes that you suggest not using it?
