Function definitions that use a bad function name (such as "-" and "=") 
are accepted if the function name already exists as an alias. For example:

$ -
dash: 1: -: not found
$ - () { echo hello; }
dash: 2: Syntax error: Bad function name
$ -
dash: 2: -: not found
$ alias -=true
$ -
$ - () { echo hello; }
$ -
hello
$
