Here is the list of built-in utilities from various shells that
have been collected on the Etherpad while discussing Bugid: #854

Reserve these names (in bug 901?):

    alloc
    autoload
    bind
    bindkey
    builtin
    bye
    caller
    cap
    chdir (alias for cd)
    clone
    comp* (anything begining with comp) - but not compress? NO: use the explicit list:

    comparguments
    compcall
    compctl
    compdescribe
    compfiles
    compgen
    compgroups
    complete
    compquote
    comptags
    comptry
    compvalues
    declare
    dirs
    disable
    disown
    dosh
    echotc
    echoti

    help Note that "help" is part of the SCCS utilities on a historic UNIX system

    history? hist?
    let
    local
    login
    logout
    map
    mapfile
    pushd
    popd
    print
    readarray
    repeat
    savehistory
    source (already reserved?)
    shopt
    stop
    suspend (needs to be intrinsic)
    times
    typeset
    whence

Given that 0001071 has been accepted, the change requested here is probably not needed. However, I think we should keep this bug open as a fall-back option in case there are objections to 1071 at some point down the line.

See note 4023 (attached to issue 1071) for an explanation why reserving namespaces
is never the right solution. Whether 1071 is finally included in issue8 or not, this
should be rejected.

In addition to the list in note 2511 there are also (that I know of)

exp (more or less the same thing as let)
fdflags (manipulate the fcntl type flags on a fd, incl close-on-exec, but also append, ...)
inputrc (define file for input mappings for line editing)
jobid (converts between % job notation and process ids)
wordexp (glob code access for libc - kind of like fnmatch() but using sh to do the work)
