Re^4: Arithmetic bug within Time:Piece?

Could someone please enlighten me if this is a (old) problem? I had no problems to store an object in a constant.

I think its probably a unclear statement, as its unlikely MSERGEANT didn't know you could write

sub ONE_WEEK() { return bless ... }
[download]

http://backpan.perl.org/authors/id/M/MS/MSERGEANT/ dates the module to 2001

perldeltas doesn't show anything relevant , perlbug neither,

But free has more candidates http://perl5.git.perl.org/perl.git/search/HEAD?pg=7;s=constant;st=free but nothing seems on point, even just looking at old constant.pm shows using references as constants ....

So maybe matt was confused at the time :) I doubt I could compile something before before 5.6.2 to check

My guess is he wanted to primarily store an integer for seconds into a constant. Since one can only bless references this would have complicated to simply get a number in nummeric context. (it's still possible with an `overload` of `"0+"` ) edit strange, his code does overloading, including `"0+"` Maybe an old version of his code didn't use `constant` but this other technique to put a immutable literal into a package variable... like `*PI = \3.14159265358979;` well who knows ... old code ... sigh Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l] [select]
