Maybe we should rephrase the ticket,
it's just a placeholder for the issue being discussed:

If you want to unset a function with a name that's not a valid identifier, use `unset -f'.

Hello,
seems like bash allows illegal function names, but refuses to unset them then:

$ function 1a () { :; }

$ declare -f 1a
1a ()
{
    :
}

$ unset 1a
bash: unset: `1a': not a valid identifier
$
GNU bash, version 4.3.48(1)-release (x86_64-slackware-linux-gnu)

The first character of a name should not be a digit: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_235
