"Undefined variable" error when testing autoloaded variables about vim-vspec HOT 3 CLOSED

Thank you for the report. It might be a bug in Vim. I confirmed a similar problem without vim-vspec. Try the following steps with vim -u NONE -i NONE -N:

set runtimepath+=path/to/bundles/autovar

echo autovar#Number()
" => Echos 12

echo autovar#NUMBER
" => Echos 12

function Foo()
  return autovar#NUMBER
endfunction

echo Foo()
" => Fails with the following message:
" Error detected while processing function Foo:
" line    1:
" E121: Undefined variable: autovar#NUMBER
" E15: Invalid expression: autovar#NUMBER
" 0

from vim-vspec.

After reading your reply I found this message and a work-around:

describe 'autovar#NUMBER'
  it 'works now'
    Expect g:autovar#NUMBER == 12
  end
end

So technically this might not be a bug, but a very strange scoping rule in Vim eval.

I am not sure if I should report it on vim_dev, but I agree that this is not a vspec problem. I'm closing it, thank you.

Thank you. I've added a note on the problem and the workaround to the document. Because it's hard to guess the scoping rule of autoload variables form :help.
