Subject: rb_eval_string_protect with correct error line number

Rubies:

rb_eval_string_protect() calls eval(), so at error time $ERROR_POSITION ($@)
gives me a useless number. I want the line number (and preferably the column
number) of the offending part of the evaluated string.

Raw Ruby does that like this:

    stwing = """
        puts 'a'
        puts undeclaredVariable
        puts 'c'
    """

    begin
    eval(stwing, nil, "yo", 0)
    rescue
      p $@
    end

That outputs ["yo:2"]

How can I get the correct error line number, using the equivalent of
eval()'s last two optional parameters, without converting my string to a
Ruby string and then calling "eval" on it?
