In code such as: > hobbes% () { for arg do print -r $arg; done; } 1 2 3 > 1 > 2 > 3 the implicit `in "$@"` added when the `in word ...` list is omitted also implicitly appends the separator term, making the above code valid. This is fairly innocuous behavior and is POSIX-compliant, so document this odd edge case rather than risk regressions attempting to change the lexer/parser code. --- Doc/Zsh/grammar.yo | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/Doc/Zsh/grammar.yo b/Doc/Zsh/grammar.yo index d2c7cd29c289287066..33aa3a4c5965771971 100644 --- a/Doc/Zsh/grammar.yo +++ b/Doc/Zsh/grammar.yo @@ -185,11 +185,12 @@ cindex(loops, for) item(tt(for) var(name) ...
