String interpolation with #{} need not use the enclosing curly brackets when
interpolating instance variables or global variables:
>> $global = 'hello'
=> "hello"
>> "the var value is #$global"
=> "the var value is hello"
>> $/ = 'oops, gotcha'
=> "oops, gotcha"
>> "the var value is #$/"
=> "the var value is oops, gotcha"
