If it's not a drop in replacement for underscore or lodash, please don't use "_".

I see nothing wrong with using "_". It's just a variable name. The first snippet of code and preceding paragraph are:

> If you prefer using highland under the name _ like is done in the examples below, you can then simply use: > > var _ = highland

So it's not like you are required to use "_". And if it is a local variable, there is no risk of colliding with Underscore.
