Positional parameters and sourced files

["Bart Schaefer" <schaefer@candle.brasslantern.com>]

Put these commands in /tmp/test.zsh:

	echo $# $*
	set a b c d e

Now:

zsh% source /tmp/test.zsh ; echo $#
0
5
zsh% source /tmp/test.zsh arg ; echo $#
1 arg
0


So "set ..." in a sourced script changes the global positional parameters
when the script is called with no arguments, but if it was called with any
arguments then it changes only the locals.  This seems a bit odd.

Bash, on the other hand, always changes the global positional parameters,
and further it throws away the local ones when the global ones are set.  I
don't have ksh handy to try.
