Hi,
It seems that the variables used in a function by default are local
anyway. Does it mean that the command `local` is never necessary in a
function if the variables are specified as local variables? Thanks.
$ cat ./main.sh
#!/usr/bin/env zsh
# vim: set noexpandtab tabstop=2:
set -v
function f {
x=1
y=(a b c)
}
declare -p x y
$ ./main.sh
function f {
x=1
y=(a b c)
}
declare -p x y
./main.sh:declare:10: no such variable: x
./main.sh:declare:10: no such variable: y

Regards,
Peng
