I like the idea of having a single syntax for all cases, but I don't like
the syntax you propose.
In my opinion, it's syntactically inconsistent, less readable and more
error prone, than the old one (sscanf based) and the FAST_ZPP one that is
already in php-master.
I would also prefer to have an ability to select which function should use
"fast" parameter parsing individually.
(You propose use "fast" for all functions, or enable it per extension)
Using "fast" parsing for all functions may significantly increase code size
and slowdown execution, but we won't know it for sure until we didn't try
it.
Anyway, if we find a good single syntax, we must be able to solve technical
problems.
Opinions and other syntax ideas would help us to do our best :)
Thanks. Dmitry.
