Do you add "Cc" (carbon copy) to me?  I add you with this mail.

Matz decided that "->" is obsolete.

I can't recreate your bug.

at my environment (on x86 linux)

I don't support "make install".  Please use "make install-nodoc"

These are knwon bugs :)

Ah, .... OK.  I'll fix it (remove obsolete "Proc" and rename
YARV::VM::Proc to "Proc")

a = [1, 2]
p [*a]     #=> [1, 2]
a = 1
p [*a]     #=> can't convert Fixnum into Array (TypeError)

You means second error?  It's new specification on Ruby 1.9.  ... I have
no idea about arrayification (it's first time I see this word) with 1.9.
