Calling block from another block raised about crystal

[asterite]

Yes, this is because blocks don't form closures yet (and they are very experimental right now and causes all kind of codegen errors). A shorter example to reproduce the above:

a = 1
f = -> { a }
f.call

But I'll keep this open until we fix it.

also, problem with passing block

def f(&block)
  yield 1
end

def g(&block)
  f(&block)
end

g { |x| p x }

nil

[yui-knk]

On 0.7.5 these codes work!

def f(x, &block : Int32 -> Int32)
  l = ->(y : Int32) { block.call(y) }
  l.call(x)
end

f(1) { |x| p x }
# 1

def f(&block)
  yield 1
end

def g(&block : Int32 -> Int32)
  f(&block)
end

g { |x| p x }
# 1

• type of &block is need
• Int is not valid, Int32 is valid

Can we close this issue?

[asterite]

@yui-knk I think that now that the semantics of the language are more defined, we can close this issue. @kostya what do you think?
