I'm not a POSIX expert, and this is the SUS, but I read:
| The format of a function definition command is as follows:
| fname() compound-command[io-redirect ...]
| The function is named fname; the application shall ensure that it is a
| name (see the Base Definitions volume of IEEE Std 1003.1-2001, Section
| 3.230, Name).
--> ("name" def)
| In the shell command language, a word consisting solely of

| The first character of a name is not a digit.
