foo = Promise.resolve \foo
bar = Promise.resolve \bar
foo-bar = -> "#{await foo} #{await bar}"

## CLI
Please stop using cli for any serious task, write scripts in **real** languages (there are so many to choose) e.g.  

    lsc serious-task.ls  
    node serious-task.js
    python serious-task.py

If you really must to use cli just add require plugin file to the command.  
But don't say I didn't warn you!

    lsc -cr livescript-transform-implicit-async/register app.ls


running

    node -r livescript-transform-implicit-async/register app.ls
