Turns out caching isn't necessary or desirable (though it is slightly faster)

Thefuck takes longer to generate aliases than it takes hell to freeze over:
```sh
time thefuck --alias
thefuck --alias 0.12s user 0.04s system 92% cpu 0.172 total
# What the fuck?
```
This can be cached in your shell's startup script `.bashrc` or whatever:
```sh
[ -n "$XDG_RUNTIME_DIR" ] && thefuck_cache="$XDG_RUNTIME_DIR"/thefuck_cache
[ -z "$XDG_RUNTIME_DIR" ] && thefuck_cache="$HOME"/.local/share/runtime/thefuck_cache
if [ ! -f "$thefuck_cache" ]; then
thefuck --alias k | tee -a "$thefuck_cache"
thefuck --alias fk | tee -a "$thefuck_cache"
thefuck --alias fcuk | tee -a "$thefuck_cache"
thefuck --alias fuc | tee -a "$thefuck_cache"
thefuck --alias fcu | tee -a "$thefuck_cache"
thefuck --alias fuck | tee -a "$thefuck_cache"
thefuck --alias fuk | tee -a "$thefuck_cache"
fi
source "$thefuck_cache"
unset thefuck_cache
```
Doing this with `--enable-experimental-instant-mode` requires some care, because doing it wrong will cause thefuck to run infinite processes until it fills up your memory and crashes your computer!
This is a zsh script. To check for the login shell in bash, use `shopt -q login_shell` instead of setopt.
```zsh
#!/bin/zsh
thefuck_experimental_cache="$XDG_RUNTIME_DIR"/thefuck_experimental_cache
THEFUCK_EXPERIMENTAL_LOCK_KLUDGE="$XDG_RUNTIME_DIR"/thefuck_experimental_lock_kludge
experimentallyinstantlylockkludginglyverylongname () {
printf %s " $$ " >>"$THEFUCK_EXPERIMENTAL_LOCK_KLUDGE"
[[ ! -f "$thefuck_experimental_cache" ]] \
&& thefuck --enable-experimental-instant-mode --alias noop >"$thefuck_experimental_cache" \
source "$thefuck_experimental_cache"
}
[[ ! -e "$THEFUCK_EXPERIMENTAL_LOCK_KLUDGE" ]] \
|| touch "$THEFUCK_EXPERIMENTAL_LOCK_KLUDGE"
if [[ -z "$(setopt | grep -i login)" ]]; then
[[ ! $(grep -qF -- " $$ " $THEFUCK_EXPERIMENTAL_LOCK_KLUDGE) ]] \
&& experimentallyinstantlylockkludginglyverylongname
# so here it is, not cached.
else
# Delete this file on startup so it doesn't grow indefinitely.
rm "$THEFUCK_EXPERIMENTAL_LOCK_KLUDGE"
fi

**Don't run thefuck --alias more than once.**
Instead: run it, then use `alias thing=fuck`.
```sh
thefuck --alias
alias fk=fuck
alias f=fuck
alias k=fuck
alias fu=fuck
```
