Actually, it would be a `-g' option to declare, and that will probably
get in there.

`declare' has the side effect of making things local to a function, if
it is used within a function.  There is currently no way to create a
global associative array while inside a function; you'd have to do it
outside the function.

Chet has said, I think, that he might consider a `global' (or similar)
keyword at some point in the future.

   It's not a bug. It's an unfortunate side effect from 'declare'
   being a duplicate of the (non-standard) typeset builtin.

   If would be much more useful (and semantically accurate), if it
   just did what its name implies, and left the 'local' builtin for
   declaring variable local to a function.

Question if bug: declaration of an associative array within a function

[Rainer Rehak]

Hey there,
is it a bug, that the declaration of an associative array within a
function does not survive till after the function, with primitive
variables on the other hand that concept works well.

Greetings
Rainer
