lazy_load() {
# Act as a stub to another shell function/command. When first run, it will load the actual function/command then execute it.
# E.g. This made my zsh load 0.8 seconds faster by loading `nvm` when "nvm", "npm" or "node" is used for the first time
# $1: space separated list of alias to release after the first load
# $2: file to source
# $3: name of the command to run after it's loaded
# $4+: argv to be passed to $3
