Puts "#{expression}" braces always needed?

Silly me! I think I was trying it with local variables. Read Mark!

The pickaxe book says (on page 51) that if the expression
is a global, class
or instance variable then the braces aren’t required.
Omitting them doesn’t
seem to work for me. Is the book wrong?

it seems to work for me

pigeon% ruby -e ‘$a = @@a = @a = 12; p “#$a #@@a #@a”’
“12 12 12”
pigeon%

Can you give an example ?
