I hope the development team will also consider adding a way in bash to
declare global variables inside a function perhaps either with an
option in typeset or declare like -g (same as zsh) and/or a builtin
function like global as similar to local.
I thought variables in functions were /always/ global unless declared
local?
It's the other way round. Regarding typeset and declare, the man page
says: " When used in a function, makes each name local, as with the
local command. " So within a function, typeset, declare, and local are
synonyms. Using 'local' outside a function is an error, so IMHO this
command is completely redundant. It _would_ make some sense, however, if
its counterpart 'global' existed, as it could help clarify the intended
usage of the variable.

$ vars () { var1=123; local var2=456; }
$ vars
$ echo "var1=$var1 "var2=$var2"
var1=123 var2=
How is that "the other way around"?
(Sorry, something went wrong with the last reply)
What I meant is that variables _declared_ in functions are always global.
