I often end up typing ' simply because it's an unmodified key on my
keyboard, unlike " which necessitates pressing shift as well.

Here's a little trick for when you have a '-quoted string that you
want to add interpolation to: just add %:

before:
'foo #{3}' # => "foo #{3}"

after:
%'foo #{3}' # => "foo 3"

I'm not saying you should do it all the time, but it's occasionally
nice to save a few keystrokes when playing around with some code.
