Hi Guilherme
You wrote that Java spec? Cool! Also very nice example of the PHP
EBNF! I think PHP needs a canonical one of those and that the parser
should be rewritten to represent said EBNF. Thats what I'm dreaming of
at least :)

As a final note, I'd like to mention that even PHP grammar being quite
simple, it is light-years more complex (due to the lack of
standardization) than other languages.
You can compare this initial description I wrote to the Java
Specification and get your own conclusions:

Hi all,
PHP grammar is far from being complex. It is possible to describe most
of the syntax with a simple explanation.
Example:
* We can separate a program into several statements.
* There're a couple of items that cannot be declared into different
places (namespace, use), so consider them as to

Hi!
But still I have to ask if I'm the only one thinking about this or is
there something I'm being completely ignorant about?
You're not the only one thinking about it. But so far nobody moved from
thinking about it to actually doing it :)

Dear internals
After enviously looking at pythons grammar
(http://docs.python.org/dev/reference/grammar.html) I keep feeling
that PHP is missing out on a lot of interesting meta projects by not
having an official EBNF.
Building your own PHP parser is _very_ hard and is PhD (Paul Biggar:)
