srfi-39 implementation

[Jose A Ortega Ruiz]

Hi.

Please find attached an implementation of SRFI-39 (parameter objects)
for Guile. Following hints by dsmith and rlb in #guile, i've implemented
it from scratch using Guile's fluids, which are already very close to
parameters (unlike SRFI-39's reference implementation, this is thus a
thread-safe implementation).

It's nothing fancy (we already have fluids after all!), but including
it would make Guile more buzzword-compliant ;-). So, I'd be glad to
transfer the copyright to the FSF (if needed; it's barely 30 loc without
comments) in case you deem convenient including it in future releases.

Thanks for your time.

Regards,

jao
