line after type declaration begins indented

[matthewleon]

for example

x :: Number

The line immediately after will begin indented. This is undesirable to me.

Removing the setlocal indentexpr=GetPurescriptIndent() line from the indentation file stops this, but of course it stops all indentation.

I can't tell if this is something unique to my vim configuration, or if this happens to everyone. I'd appreciate any advice you can give for further debugging.

I've removed all plugins except this one, and the behavior continues. This is in Vim 8.

I can confirm this behaviour in vim 8. My vim configuration is:

call plug#begin('~/.vim/plugged')

Plug 'scrooloose/nerdtree'
Plug 'kien/ctrlp.vim'
Plug 'bling/vim-airline'
Plug 'vim-airline/vim-airline-themes'
Plug 'tpope/vim-fugitive'
Plug 'valloric/youcompleteme'
Plug 'pangloss/vim-javascript'
Plug 'mxw/vim-jsx'
Plug 'flazz/vim-colorschemes'
Plug 'nathanaelkane/vim-indent-guides'
Plug 'scrooloose/syntastic'
Plug 'bling/vim-bufferline'
Plug 'tpope/vim-surround'
Plug 'elmcast/elm-vim'
Plug 'purescript-contrib/purescript-vim'

call plug#end()
