Will Julia ever fix its "using ..." latency problems?

General Usage Performance

NOTE: Im not an expert :slight_smile:
But It works with jupyter in general, among other stuff, It allows you to have a textual working representation of a notebook, I have use it for julia and python to produce .py and .jl runnable scripts. It just add a bunch of comments lines to store important info such that where a cell starts and ends or whether it is a markdown/code cell. After that you can use the .jl/.py/etc file alone to start a new session or in synchronization with a .pynb file. You can even drop the .pynb completely and work just using the common text files, but you lose the cell output of previous sessions.

Here and example

# -*- coding: utf-8 -*-
# ---
# jupyter:
#   jupytext:
#     cell_metadata_filter: -all
#     formats: jl,ipynb
#     text_representation:
#       extension: .jl
#       format_name: light
#       format_version: '1.5'
#       jupytext_version: 1.3.2
#   kernelspec:
#     display_name: Julia 1.1.0
#     language: julia
#     name: julia-1.1
# ---

# +
println("How you doooing?")
# -

This is a .jl file equivalent to a .pynb with a single cell with the print statement.

I primarily use it because the .pynb is too noise for version control.
