But as documented here for best peak performance TruffleRuby JVM should be used.

SEGV occurs in the code below.

def m
  i = 0
  while i<30
    i += 1
    yield
  end
end

m{}

The README doesn't mention anything about compatibility, but it seems worth having at least a sentence about it.
Does it run RubyGems/Bundler/Rails? Does it have the Ruby standard library? C extensions?

TODO: Support class variables.

Currently we can accept super with arguments delegation only when super exists in a method scope.
We must support super in a block scope.

a = [1,2,3]
b = []
10.times do
    b.prepend(*a)
end
puts "#{b}" 

CRuby: [1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3]
monoruby: [[1, 2, 3], [1, 2, 3], [1, 2, 3], [1, 2, 3], [1, 2, 3], [1, 2, 3], 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3]

LoadConst insn returns wrong value when base exists because base is not guarded.

module M
  def initialize
    puts self.class::C
  end
end

class A
  include M
  C = 100
end

class B
  include M
  C = 200
end

A.new # => 100
B.new # => 200  but monoruby gets 100 currently.

In Ruby method call, when all conditions of

1. the callee method does not have keyword params
2. at least one keyword argument exists
   met, keyword arguments are converted to a Hash object and the Hash is passed to the callee method as the last positional argument.

Currently, monoruby is not compatible with this behavior.

def f(a, b, *c)
  puts "a:#{a} b:#{b} c:#{c}"
end

f("a", 42, 1000, x:100, y:200)
# => [Ruby] a:a b:42 c:[1000, {:x=>100, :y=>200}]
#=>[monoruby] a:a b:42 c:[1000]

TODO: Support class definition with class names which have prefixes.
