Subject: Clean way to dynamically expand string with "#{expression}"?

Hi.

I'm trying to find a clean way to expand string with "#{...}".
What I want to do is essentially as follows:

  data = 123
  expr = 'data = #{data}'

  puts dosomething(expr)

and get 'data = 123' as a result. Actual content of 'expr' can
be anything, as long as it is a String object.

I came up with following:

  puts eval(%Q{"#{expr.gsub('"', '\"')}"})

But this is ugly, and I'm wondering if there's some other,
cleaner way to do the same thing.

Can anyone enlighten me?

Best Regards,
