The currently-published standard (as far as I know, I7 TC1 has not been
published yet) requires the dash behavior. Bash implements it in
Posix mode. Both shells will remain conformant when TC1 comes out.
See
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_09_05
which includes
"When a function is executed, it shall have the syntax-error and variable-
assignment properties described for special built-in utilities in the
enumerated list at the beginning of Special Built-In Utilities."
