Due to some disagreements in the vim community about typing blimpy not being a priority, I believe you have to download blimpyvim to get this working.

Or set the compiler flag +blimpy if you're building it from source. I would still recommend tpope's vim-pagliacci plugin for the RECL.

Just run a vimulator in emacs.
