pyenv init slows down the shell startup a bunch (by about ~100 ms!)

Just checked on my laptop. There the difference is larger (it is a slower and older computer): 160.4 ms down to 16.5 ms.

I have the same issue as well on zsh. Running pyenv init - or $(pyenv init --path) adds around 300 ms (I go from 80 ms to 380).

I figured out a workaround:

pyenv() {
    eval "$(command pyenv init -)"

    pyenv "$@"
}

This will initialise itself on first use and overwrite with the slow implementation. As I don't use pyenv very often (I mostly do Rust these days) this works for me. For even less overhead, put that in a zsh autoloadable file so it isn't even parsed until it is needed.
