Subject: Delayed quote expansion

I'm sure the answer to this will seem simple once I see it.  Right now 
it eludes me.

How can one have a string object like this...

a = '#{some_value}'

and have it get evaluated as a double quoted string (with the value for 
some_value being automatically replaced) at a later time?

I would prefer that it is evaluated in context from which it is called.

I would like to do something like this...

def func(param)
  test = 42
  puts param.quote_substitution
end

func('my number is #{test}')    #=> "my number is 42"
