Paul,
This should be
eval {require SVN::Client; };
use() is a compile-time directive, not runtime.

Hi Paul,
could you add a check for SVN::Client and skip the test when there is no

In languages/lua/lib/thread.pir, I create a Lua thread type by extension of
Parrot::Coroutine.
So I add a lot of methods for Lua type, but I think that 2 of these methods
could be integrated in Parrot::Coroutine :
- __clone
- __get_pointer (equivalent of get_pointer() in src/pmc/sub.pmc)

Are you sure? I see "&" as "limiting; sub" and "|" as "enlarging;

To me, "&" is connected to multiplication (and inproduct, statistics,
fuzzy logic), and "|" to addition (and outproduct).

Hello,

When creating a new program, you are not allowed to pick-and-choose
what you want from other programs sources as that would be a copyright
