No, it fails if the argument is both a function AND a variable.
imadev:~$ is_defined3() { { declare -p -- "$1" && ! declare -fp -- "$1"; }
2>/dev/null >&2; }
imadev:~$ declare -p foo
bash: declare: foo: not found
imadev:~$ is_defined3 foo ; echo $?
1
So far, so good. But....
imadev:~$ foo() { echo foo; }
imadev:~$ foo=bar
imadev:~$ is_defined3 foo ; echo $?
1
