we might have both. now all functions are global and this is ok (if people
knew about it). in the future when scope comes in - a modifier before the
function keyword will solve the problem with scoping and more - everything
will be kept backward compatible.
say that the modifier is local or static or...

Is there a need for nested funcitons? I don?t think so.

How about a simple check:
function outer()
{
if (!function_exists('inner')) {
function inner() {
}
}
}

sure, this fixes the symptoms,
bit if noone can think of a reason or situation where nesting
functions would make sense i'd like to have this 'feature'
removed
it's confusing, unseless IMHO and leaving it possible will
block any chance to implement it the way Pascal or gcc in
extended mode handle it with the inner function only
visible within the scope of the outer one ...
