Warning on swapping array elements

[kaosf]

Sample file ruby_hl_lvar.vim-error-example.rb:

x = [10, 20]
x[0], x[1] = x[1], x[0]

Warning messages:

"ruby_hl_lvar.vim-error-example.rb" 2L, 37C
WARN: Unsupported ast item in handle_massign_lhs: [:aref_field, [:var_ref, [:@ident, "x", [2, 0]]], [:args_add_block, [[:@int, "0", [2, 2]]], false]]
WARN: Unsupported ast item in handle_massign_lhs: [:aref_field, [:var_ref, [:@ident, "x", [2, 6]]], [:args_add_block, [[:@int, "1", [2, 8]]], false]]

Open the file at first, and then execute :e to reload (reopen) it... The Vim window CRASHES 😨

x = [10, 20]     type  :help sponsor<Enter>    for information
x[0], x[1] = x[1], x[0]

This is my environment: https://gist.github.com/kaosf/5f2fa08a406984d8f3e2

I made some changes:

• Disable warnings by default
• Fix logging method

The problem would fix.

I pulled and checked the commit 5780bee yesterday. When opening that Ruby file first, no warning messages are shown. But execute :e after that, some messages appear.

Now, I found the new commit cb310ba.

Sorry, but nothing changed on my Vim 😢

At first, the configuration of let g:ruby_hl_lvar_show_warnings = 1 makes no changes.

英語の自信がナッシングすぎるので日本語で補足させてもらうと，最初開いた時は何も出ないんですが後から :e するとやっぱり警告文が表示されてしまいます．
