can I give a +1 for you making a request to start a RFC on the matter ...
I'm sure LKS will give you perms to set up one on wiki.php.net/rfc.
some of your ideas have merit, some maybe not, others are likely to be impossible
to implement from a performance technical POV.
either way, having a work-in-progress RFC for these ideas would give a solid point
of reference for discussion. all/any of your ideas have much more chance of
making inroads if implementation/BC/performance/syntax details/proposals are
properly documented.
I think adhoc discussion via the mailing list leads generally nowhere with this
type of thing, there is too much noise and it's nigh on impossible to grok where
the status quo is at or what current the proposal might be.
some of your points lean purely to making php more consistent, they may even
be self-evident (e.g. completion of things your able to typehint) but nonetheless
even that needs solid argumentation in order to win the minds of the guys that
will/may end up implementing it.
RFC is the way to go. I for one would gladly take time to read/review/comment, if
nothing else it's interesting.
actually thinking about it you might consider thinking in terms of a collection
of RFC's (your ideas cover quite a lot of ground/scope) in order to maintain tight
focus.
