libretto and libguile

[Klaus Schilling <Klaus.Schilling@home.ivm.de>]

I've found a LGPLed library called 'libretto' which implements some container
data types like linked lists, dynamic strings/arrays, binary search trees,...
in ANSI C. Quoting the introduction from the info file:

------------------------------------------------------------------------
The `GNU C Library Reference Manual' says

     The C language provides no built-in facilities for performing such
     common operations as input/output, memory management, string
     manipulation, and the like.  Instead, these facilities are defined
     in a standard library, which you compile and then link with your
     programs.

The contents of the `standard' library are defined by the ANSI and ISO C
committees for general C environments, with additions by groups such as
the Open Group for Unix and by the POSIX committee for Unix-like
operating systems.  However, some of the most commonly-desired functions
and data structures are not provided by these standards, or if they are,
the required complexity of the implementation is insufficient for a
number of applications.

   This is where Libretto(1)
comes in.

Anyone have a rough idea if it would be potentially dangerous to use libguile 
and libretto together, by for example wrapping scheme lists into libretto 
lists? For a bloody newbie it sounds very tempting to use Lisp wrappers 
communicate with a portable implementation of lists in C, but when considering
that even different Lisp dialects have communication with each other (as the 
guile<->elsip discussion showed), it could be more likely that someone with 
the experience of Stallman went through the roof when seeing such a messy 
approach.
