It is intentional. If you want bash to run in POSIX mode, you should use the 
`POSIXLY_CORRECT' variable or the `--posix'
flag.

| address@hidden:~$ POSIXLY_CORRECT=y bash -c 'function 1a() { :; }'
| bash: `1a': not a valid identifier

And as Andreas mentioned, in general you should use `unset -f' if you want to 
operate on functions. Otherwise you risk
conflict with a variable name.
