To clarify, we don’t no insist that everyone write Julia code without underscores. It is a discipline beautifully explained by DNF to which Base Julia strives to adhere in its public API. In internal functions and in my own code I use underscores all over the place because the factoring of the code doesn’t matter so much. Not all code needs to be reduced to its most atomic elements of design, but that’s what we aim for in the Base language.
