Warning: I will close the issue without the minimal init.vim and the reproduce ways.

I know I need to follow the message but sometime I just need simple modification and would like to ignore the message. So forever warnings are too annoying in that case.

Expected

The warning message showed only ONCE.

Probably put some flag on https://github.com/Shougo/deoplete.nvim/blob/c832f9d176c78a439617d39a6b0393e476a88868/rplugin/python3/deoplete/source/omni.py#L52-L63 to ignore further warnings?

Hello @lambdalisue , i have same issue with php completion and padawan. I think the problem appeared with this commit.

Had to force plugin on previous commit ( 5fc5ed7 ) to get working again.
