Hiya,
$ bash -c 'foo() { echo a >&3; } 3>&1; foo'
a
$ ksh -c 'foo() { echo a >&3; } 3>&1; foo'
a
$ zsh -c 'foo() { echo a >&3; } 3>&1; foo'
foo: 3: bad file descriptor
$ ARGV0=sh zsh -c 'foo() { command echo a >&3; } 3>&1; foo'
foo: 3: bad file descriptor
It looks like zsh evaluates the redirection at the time the
function is defined rather than when it is called.
It's OK when declaring the function as
foo() echo a > file
or
foo() (echo a) > file
instead of
foo() { echo a; } > file
