Hi all,
Following up our recent "Namespaces" chat, I'd like to get the ball
rolling on the subject of the builtin functions namespace idea.
I propose to write an RFC to outline the overall mechanism, and give an
*initial* list of functions to include in it. I say initial, because
the entire point of the mechanism is that's where we'll be adding any
of the "simple, acts like a function" things in future, so this very
much doesn't need to be a full complete list; just a few bits and
pieces to get us started.
To that end I am looking for answers to such questions as:
* What should it be called? Votes on:
use functions 'abc', 'xyz', ...;
use function ...; # because function::abc reads
nicer
use builtins ...
use builtin ...
use std ...
This name would have to be well-behaved as a regular CPAN module,
because the module needs to be dual-life, available to install from
CPAN so older perls can still use the functions it contains.
I therefore feel it should be a single toplevel name, and
all-lowercase. I have no strong thoughts about singular vs. plural
as a name.
* What *initial* set of functions to put in it? [again see comment
above]. So far I'm thinking:
trimmed($str) # which started this whole discussion off
refaddr($ref), reftype($ref), etc... # from Scalar::Util
getcwd() # Seriously, because currently we have one in
Internals:: of all places, and that really needs to
disappear.
* Any other important considerations we've missed
Try to keep comments brief - remember this is a *pre*RFC chat of
"should we write this RFC at all?", rather than fine-tuning inner
details of the idea. That can be handled separately as comments on the
actual RFC as it gets written.
Also try to avoid comments of "please add ${my pet favourite function}"
- as I said this is just an initial list of function names to get the
mechanism itself in place. Once we have something, we can take ideas on
more functions on a case-by-case basis.
