Subject: String#dump and interpolation

I'm working on a tiny code generation problem.

I like #dump because it puts things in readable form:
"\002\004\n" and so on.

I'm generating Ruby code from Ruby. I'm inserting some vars
and expressions in the strings:

   name = "foo"
   str = 'My value is #{' + name + '}'   # Note the single quotes

However, when I do a dump of this, it marks the interpolated value
with a backslash (as a favor to me):

   "My value is \#{foo}"

I want all of the other features of #dump, without the backslash
in front of interpolated values. How can I get that?

For now I'm just changing '\#{' to '#{' -- but what if my string
contains a real '\#{' someday (always a possibility in code
generation and metaprogramming)?


Thanks,
Hal
