Research direction

Start with the :echo : example and inspect autoload/vimlparser.vim around line 3391, where the issue reports the behavior. Determine the intended handling for this input and whether one error should replace the two currently reported errors; the work is complete when the chosen behavior is defined and consistently produced.

Description

:echo :

Vim throw two errors for this statement.

E121: Undefined variable: :
E15: Invalid expression: :

https://github.com/vim-jp/vim-vimlparser/blob/b5f83738ba1baf012b9910487e5e38d577a916a5/autoload/vimlparser.vim#L3391

If modify this part to 1, error E121 is returned. We should design behavior what error should be returned.
