Hello Internals,
I opened the vote about Stricter implicit boolean coercions as
announced. The vote will run until 2022-06-20.
Discussion: https://externals.io/message/117732
RFC: https://wiki.php.net/rfc/stricter_implicit_boolean_coercions
Best regards,
Andreas Leathley
The vote has been closed, the RFC has been declined with 14 to 3 votes.
It would have been interesting to get some more feedback on why people
voted No - some took part in the discussion, but most didn't. My
assumption is that most didn't find this important enough, especially if
strict types is not affected. While I think the RFC would have helped
identify obvious bugs (and I find the current behavior of PHP with
boolean coercions less than ideal), I can see an argument for voters to
not see it as something important enough to change the language, as the
problems this RFC would have highlighted can be avoided altogether.
If anybody still wants to give some insight on these reasons or a way to
improve boolean coercions in another way, I would be happy to hear it.
Otherwise thanks to everybody who took part in the discussion, it was an
interesting experience.

Indeed... Of those who did, I have retained the following arguments
(sorry in advance for any omission, approximation or
misinterpretation):
- no impact analysis (but seems difficult...)
- it would increase the discrepancy between e.g.
if ($x)and
takes_bool($x)(already existing for non-scalar $x [okay VS
TypeError], but now for scalar $x too [okay VS deprecation notice]) - the deprecation should apply to all floats (even 0.0 and 1.0)
because floating-point equality is risky - the deprecation should include the string "0" (VS empty "")
because it's a recurrent WTF (and maybe even in all implicit boolean
evaluations [e.g.if,&&etc.] too) - we should rather deprecate
takes_bool($string)and
takes_bool($float)totally (i.e. all strings and floats), and also
takes_string($bool)andtakes_float($bool)(but maybe don't need
to changetakes_bool($int)at all)
Note: I think that generally there can be arguments in both ways...

I agree ;(

Thank you ;)

Sorry I don't have better ideas... Maybe others will?
