Hello,

Tried out librend on YARV, and what tests I managed to get running were
very promising (30-50% avg FPS speedup!)


Found some bugs too (the YARVCore::VM::Proc vs Proc -issue was reported
already so not repeating it here):



1. found when compiling rubysdl, mkmf.rb contains code like:

for d,*f in [[1,2,3]]
...

kig@bauhaus:~$ ruby1.8 -e 'for d,*f in [[1,2,3]]; p d,f; end'
1
[2, 3]

kig@bauhaus:~$ ruby1.9 -e 'for d,*f in [[1,2,3]]; p d,f; end'
[1, 2, 3]
nil



2. had some incompletely arg'd blocks in my code and ran into:

kig@bauhaus:~$ ruby1.8 -e '[[1,2,3]].map{|a,b| p [a,b]}'
[1, 2]

kig@bauhaus:~$ ruby1.9 -e '[[1,2,3]].map{|a,b| p [a,b]}'
[2, 3]



3. define_method has bug with splat args

kig@bauhaus:~$ ruby1.8 -e 'class Object; define_method(:foo){|*args| 
p args}; end; 0.foo(1,2,3)'
[1, 2, 3]

kig@bauhaus:~$ ruby1.9 -e 'class Object; define_method(:foo){|*args| 
p args}; end; 0.foo(1,2,3)'
-e:1:in `<main>': wrong number of arguments (3 for 0) (ArgumentError)



4. method_missing and blocks

kig@bauhaus:~$ ruby1.8 -e 'def method_missing(m,&b) b end; p f{}'
#<Proc:0x00000000@-e:1>

kig@bauhaus:~$ ruby1.9 -e 'def method_missing(m,&b) b end; p f{}'
nil



x. YARV GC runs take longer than Ruby1.8 GC runs (not really a bug) 
  (ruby1.8 GC run: 45fps -> 17fps, YARV GC run: 60fps -> 10fps)
