Re^6: Determining the minimum representable increment/decrement possible? (Perl's scanf broken?)

Grr. I had a notion to try and work out what code Perl was actually using to parse doubles and 'forgot' my rule of the last few years: don't go looking in the recent perl sources; it will only piss you off.

It pissed me off. It used to be that you could compile Perl to use stdio, and I thought I might do that for 5.22; but apparently that is not longer possible!

Perl is still my go-to language for getting stuff done in a hurry; and in many cases even when the program has ultimately to be written in some compiled language, whether for speed or to satisfy some other requirement, I still use Perl to prototype and only convert to C or C++ or D or whatever once I have the code working.

But for the last few years, the P5 development has become introspective, even introverted; titivating instead of innovating; throwing any weird idea that comes up into the code base only to remove it a build or two later. I've lost track of the number of "experimental" additions that have come and inevitably gone.

It's just a shame that PerlIO isn't so easily back out and discarded! :(

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice. Not understood.

I hadn't thought of building perl without USE_PERLIO. That would have been interesting - and I agree that it's a pity that the option has been taken away. Cheers, Rob	[reply]

I hadn't thought of building perl without USE_PERLIO BTW, in a recent email I suggested to Jarkko Hietaniemi that building without USE_PERLIO might be helpful re perl's problems with text-to-float. He said "I don't think the float conversions have anything to do with perlio as such. Look at numeric.c." Cheers, Rob	[reply]

Only two experimental features were removed: Passing a reference to `key`/`values`/`each` I don't know why that was released in the first place given it was known to be broken before it was even coded. `my $_;` It was causing code like `apply { s/foo/bar/ } @a` to break in a manner that was confusing for too many. Smart-matching and `given`/`when` have been experimental for a while, but they are not dead. The subject came up again this week. There are strong intentions to fix it.	[reply] [d/l] [select]
