All,
Anybody can write an RFC and call a vote whenever they want within the
guidelines set forth for RFCs.
It would be much more productive to get the RFC written and to provide
suggestions on improvements (e.g. syntax choice, default options, ways to
customize), rather battling against it. Or stay quite and vote no. Or do
both.
I am personally against this idea as it stands but maybe there is a middle
ground and maybe some good can come of it. For example, autoloading
functions.
As a suggestion:
Perhaps the ability to register a default stream filter for the default
output buffer paired with file level declarations and/or context tagging
within blocks is a possible solution. So something like:
declare(strict_types=1; output_filter_args=['label' => [ENT_QUOTES |
ENT_SUBSTITUTE]]);
// must be constant scalar expression?
// Would be passed in directly as is, the choice for an array with context
aware keys/values is up to you
register_output_filter(function($buffer, $label) { }, 'label'); // should
have similar API to spl autoloading, with multiple callback stack
<?label:="string"; ?>
----
Something like this would start to solve some of the problems of context,
default arguments, etc.
I think functions to set the filter options might be better but using
declare makes it easier to limit to current file scope and ensures
consistent placement at top. Also I realize I said to use stream filters
and I've used a closure here. Stream filters are complex due to the whole
bucket brigade/continuous data stream thing, but have the advantage of
being much more performant and resource friendly. Maybe allow both types?
Simple callbacks for ease of use, stream filters for performance and
complex stuffs.
TL;DR: what's your account? Let's give RFC karma and vote it down if you
don't want it.
