Summary: Nested Functions are BAD, they make for inefficient
debugging
Status: Bogus
Type: Feature/Change Request
Package: Feature/Change Request
Operating System: Any
PHP Version: 4.0.4pl1
New Comment:
nested functions make for grate walkers in recursive functions
BUT ! ONLY
if the scope is limited with in the outer function (witch it isn't)
AND can use same variables as outer function

brackets are used for other controll structures as well, so disabling
nested functions do not solve the problem. ->bogus

If you have a missing close-bracket "}" somewhere in your code, the PHP
parser tells you that the error is at the last line. If you have a
multi-hundred or thousand line file, this makes life a bitch.
Rasmus tells me that the reason for this behavior is because functions
can be nested, which means that:
function a
{
function b
{
}
}
is OK. This is a silly feature. Why do you have it, for scoping
reasons? It means that you can't effectively tell where syntax errors
occur.
Suggestion: Either make nested functions turned off by default but you
can turn them on with a PHP global variable, like
$PHP_BIZARRO_NESTED_FUNCTIONS = 1;
or
have the parser syntax set up so that it marks where a possible syntax
error occurred (IOW it sees a possible nested function, but it could
also be a syntax error), and if it reaches the end of the file with a
missing "}" or two, that it displays the location where it parsed the
nested function.
