# vim: ft=zsh
#
# Executes commands in every top-level or login shell
#
# ATTENTION: This differs from usual zsh behaviour! In addition to traditional
#            login shells, this is also sourced by any top-level ($SHLVL=1)
#            non-login shells. (In the latter case, from zshenv)
#
# This is useful because it only gets executed once for any given tree
# of zsh-processes, saving resources on sub-shell invocation while still
# providing a consistent environment in login and non-login shells.
#
# Then why also source it in non-interactive shells?
# Because it prevents desync between scripts and interactive prompts.
# Ever tried to debug a script and ended up with "But it works in the prompt!"?
#
# For code intended for login shells only, use zlogin instead.
