> Exactly my feeling. When it comes to dealings with 15+ MB codes (after
excluding all 3-rd parity libraries), ambiguity problem becomes real even
now. It's hard enough to think of good name for 2 similar, but different in
realisation modules, so that you understand what they are for and to
understand what is different between them. I deal with 3 projects 50 MB +-
in size every day, jumping from one to other sometimes few times a day. such
projects 100% have large amount of variables named equaly. If you begin to
implement namespace support and access them outside namespaces, it becomes a
nightmare to understand what it accessed.
I see two solutions:
1). Change the separator.
2). Don't allow function, class, constant and variable naming same as
namespace name. Make it a fatal error. Then this will be solved.
Other options like throwing something away or make an ambigity resolution
mechanism personaly me don't make happy. Throwing something away leaves us
with something half working. Ambigity resolution mechanism makes us to
remember what is what (scrolling up and down tens of times a day is realy
disturbing the work), but is for sure better than first one.
If we combine all good things from all proposals, we can get one big solid
thing. Just my IMHO, but still:
1). Change the separator.
2). Make resolution to global classes, functions, constants first and if not
found - then to namespace. But realy, may be use self to point to namespaced
function, class, method ? Same as $this in classes. That seems logical,
because PHP is already using such mechanism.
3). Don't allow ambigity naming. Die with E_FATAL in such cases, don't allow
thouse coders to write bad code, please do! I beg you!
I don't know how parser works exactly, but maybe constant ambigity could be
resolved by patch, witch resolves constant values at compile time. If that
can't be done, than issue E_FATAL.
Just my IMHO. Please, don't make a holly war of my post. I wount argue with
holly war responces. Just tell me where I'm wrong and if that's because of
implementation difficulties - explain, I will understand that techno bable
:)
