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."
