function <!> in Shen YACC

[josef...@gmail.com]

Tried to use  it ,but got error

(16-) (defcc <asbs>  [a <!> ] b := <!> ;)

<asbs>

(17-) (compile (function <asbs> ) [ [a 1 2 3] b])

The function COMMON-LISP-USER::<!> is undefined.

<asbs>

(1-) (compile (function <asbs> ) [ [a 1 2 3] b])

[1 2 3]

But the OS version fails.  I haven't looked at the OS version for a year now.   People stopped funding the maintenance so I stopped doing the work.  I'll mail a patch for it now and I'll send you it by email before I get round to mounting it.

This is occurring because <!> is not external to the `shen` package. This works:

(1-) (defcc <asbs>  [a shen.<!> ] b := shen.<!> ;)
<asbs>

(2-) (compile (function <asbs> ) [ [a 1 2 3] b])
[1 2 3]

This patch fixes this:

I forgot about this issue until I saw an email today with defcc snippets in it.

I haven't merged it yet, just waiting for someone else from the
committee to review it.
