Problem Statement

A block comment begins with a   beginning delimiter   and ends with a   ending delimiter,   including the delimiters.   These delimiters are often multi-character sequences.

Strip block comments from program text (of a programming language much like classic C). Your demos should at least handle simple, non-nested and multi-line block comment delimiters.
The block comment delimiters are the two-character sequences:

Sample text for stripping: Ensure that the stripping code is not hard-coded to the particular delimiters described above, but instead allows the caller to specify them.   (If your language supports them,   optional parameters   may be useful for this.)

Let's start with the solution:

$ include "seed7_05.s7i";

const proc: main is func
  local
    const string: stri is "\
        \  /**\n\
        \   * Some comments\n\
        \   * longer comments here that we can parse.\n\
        \   *\n\
        \   * Rahoo\n\
        \   */\n\
        \   function subroutine() {\n\
        \    a = /* inline comment */ b + c ;\n\
        \   }\n\
        \   /*/ <-- tricky comments */\n\
        \\n\
        \   /**\n\
        \    * Another comment.\n\
        \    */\n\
        \    function something() {\n\
        \    }";
  begin
    writeln(replace2(stri, "/*", "*/", " "));
  end func;
