Neat. :) One nitpick with the new man page phrasing though: | Create parameters in global scope, not in local scope. That's not quite accurate, as was also explained by the old explanation for the 'global' command which was patched out: typeset -g "does not allow a function called from another function to access a parameter at truly global scope, but only prevents putting an accessed one into local scope." IOW, it may still inherit the enveloping local scope from a calling function. - M.
