Connecting 2 processes by a pipe

How one can connect two processes by a pipe like "cat file | wc -l"?
I read "9.16 gauche.process" section of the manual but still can't get it.

expt hangs

I think the expression (expt 1/500029 362880/3) causes Gauche to hang.

write-object from write vs. from display

Hi.  According to gauche manual,

     When `write' and `display' encounter an object of a user-defined
     class, they call the generic function `write-object'.

The same generic is called for both methods? How do I make my objects
react differently to 'write' and 'display'?

c-wrapper doesn't play with the module system?

Hi.  Sorry if this is a frequent question, but I couldn't find info.
I'm using ncursesw with c-wrapper like this:

  (use c-wrapper)
  (c-load-library "libncursesw")
  (c-include "ncursesw/curses.h")
  […]
  (use gauche.collection)

From the way the module system works, I'd expect a symbol exported by
both the C libs and the "collection" module to be bound to the module
in the last "use" clause, but these aren't the results I get:

  gosh> filter
  #<closure (make-c-func loop239)>
  gosh> (with-module gauche.collection filter)
  #<generic filter (2)>
  gosh> (filter (lambda (i) (lisp? i)) '(scheme ruby cl haskell lolcat))))
  *** ERROR: wrong number of arguments: filter requires 0, but got 2

profiler overflow

Hi all.

The profile option of gauche is really useful.
But for long running processes, the call counters overflow easily.
Is there any fix for this?

Here is an example output with overflowing counters:

a little question about wiliki

I hope it is the right place to ask.

Is there a way to get the name of the current page from within a virtual page?

for example if I call the page wiliki.cgi?p=RSS_myblog

I want to be able to use the string "myblog" from within 

(define-virtual-page (#/^RSS_/ (_))
...

Any help will be greatly appreciated!
