R7RS-large aliases for srfis

[craven@gmx.net]

Hello ;)

Would it be possible to add the r7rs-large aliases for existing srfis?
For example, srfi-1 should also be loadable as (import (scheme list)).
If there is no existing mechanism in kawa for aliases, something like
the following would suffice:

(define-library (scheme list)
  (import (srfi :1))
  (export xcons ...) ;; just re-export all identifiers
  )

chibi does exactly that ;)

Would be great to help with writing portable(r) code.

Greetings,

Peter
