It is difficult to guess what you want to achieve. What it looks to me 
is a design opposite to the customary approach:

     abstract code source  (generic and/or tagged)
       /        |       \
      /         |        \
   string   text_file   stream

Since string and file cannot be derived, in a tagged case some mix-in is 
used.

The parser from simple-components has multi-line and single-line 
sources. A single-line source can be set on a string. Multi-line source 
is for files and streams.
